NEED A PLUMBER? WE’RE IN YOUR TERRITORY!

Leak Detection

Hello everyone, it’s Richard at Plumbdog here!

I wanted to do a short video just to show you guys how to check for water leaks. It’s early October here in Perth, Western Australia. We’re in a suburb called Como and as you can see from the sky, the sun is starting to shine, and officially we can turn Retic on at the start of spring. Personally, I like to leave it until a bit later because it’s still been quite rainy, but I’m just going to walk you through the sequence of events of how to turn your Retic on.

If you’re turning your Retic on for the first time this spring, it’s a good idea to check for water leaks following your first switchover. We find that a lot of people realise that they’ve got water leaks this time of year after turning their Retic on. So rather you know now, than get a very expensive bill in the post from the water corp informing you that you’ve got a leak. It’s going to show you a couple of quick steps that you can do yourself to check for leaks. Now that you’re Retic is presumably back on.

In here, we’ve got the main controller for the Reticulation. I’m just in the garage and as you can see, the dial there is put in the off position. The Retic has been off all winter, so it’s time now to turn the Retic back on. So just to stick with the existing programmes that were in there last year. Just simply turn the Retic setting onto run. That’s basically going to be in line with the settings. There are all different date and time settings to choose from. This property’s Retic days are Thursday and Sunday. We’ve got start times and what have you, so I don’t need to go into that, but basically, now the Retic is on.

With the Retic on, I just come outside to the water metre at the front and I’m just going to lift the cover. As you can see, the numbers at the top which is the reading of the meter that the Water Corp will take for your bills, and then on this type of meter, this needle here that spins around is really the one we’re looking for. It’s on number six at the moment and it doesn’t appear to be moving so I’m pretty confident there are no leaks on that. A good test to do would be to just keep your eye on it and to test for five minutes and then see if the needle moves off number six. If it does, obviously it might indicate that there is a small leak. But basically, one full turn of this needle here is one litre. So if it does move a tiny bit we’re talking about a tiny amount of water. So looking at that it looks like we are good.

Okay, so as you saw, there are no leaks there, but I’m just here with Rhyse and he’s just got a quick idea of something we can show you. We’re going to turn the camera around and you can see Rhyse. Hey Rhyse!

I’m going to run the tap slightly to imitate the leak to give you guys an idea of how much the needle will move in retrospect to how much water is coming out of the tank. So let’s pretend that’s a small leak, and then we’ll go see if the needle is moving around at the meter to give you an idea.
So we’re back at the needle, and with the naked eye, you can’t really even see it moving, but over a five-minute test you might see it move. Rhyse is going to bump it up a little bit, and yeah, you can see it moving a little bit. So hopefully it gives you a bit of an idea of the size of the leak based on the movement of the meter. It’s not a lot of water, and when it is dispersing into the ground or something, it’s not very obvious. It’s pretty easy for it to get away from you.

Alrighty, hopefully that helps. So regardless of whether it’s the time of year when you turn your Retic on, it’s always a good idea to go outside to your water metre. Once everything is off inside the house, just have a quick look and if your needle is moving, it could mean you’ve got a leak. If that’s the case, obviously you know who to call — Rich and Rhyse from Plumbdog!
Alright, thanks for watching, guys. I hope that was helpful and we’ll catch you on the next video. Take care, bye.

Hot Water Storage

Hello everyone,  it’s Richard at Plumbdog here!

I’m out at a property here in Nedlands, Western Australia and the unit behind me are having an issue with their hot water. According to the phone call between the customer and our reception, they’ve got hot water but it’s intermittent and it keeps tripping at the main power.

The first thing we do is turn the hot water on any tap in the house and check the temperature to work out what we’re dealing with, is the water cold, is it warm or is it hot and in this case – it’s cold.

Okay, so here is a Rheem 80 litre electric storage hot water system. My initial thoughts are this system is quite new it looks to be installed well and correctly by others. I’m just confirming the date of manufacture on the side there being 2020, the unit seems to be installed legally, correctly being in a safe tray that even terminates to outside so it looks to be new and installed well.

The next thing I want to do is just observe the electrics and the power connection. It seems previous people to me have butchered the unit get in the front panel off there.

I’ve never seen the pop rivet actually pulled out the system before and here is my electrical testing pen. I just want to work out whether or not we’re actually got power to the system, which we don’t, so now I’ll go outside to the main fuse board to have a look at what we’re dealing with.

As you can see the red one on the left there is the main power switch that’s on and we’ve got the hot water system one there which is off so we turn that on like all of the other switches. Now we should be getting power to the system, which we are so the water was cold because there’s no power to the system.

Investigating further, I’ve noticed that this main supply there is a lot smaller in size than what’s in the system. I’m not an electrician but to me that looks like 1.5 mil lighting cable that’s being used.

See the physical size of that being smaller in comparison to what’s inside being two and a half millimetres? There’s a Rheem electric hot water system installed under the stairs and the plumbing looks really good on it. The installation is probably only about two years old so from a plumbing perspective I really can’t see anything.

I’m not an electrician but I’ve got a pretty good idea about what we should be seeing so as I as I highlighted, you can physically see the difference between the cable sizes there being two and a half millimetres, I believe, inside the system but then the mains feed to the system looks like one and a half millimetres to me. Again, I’m not an electrician but um but there’s something a bit suspect there so I’ve spoken to our electricians that we use regularly.

Thanks to technology, I’m going to send them some photos and some videos of it and they agree that cable does look undersized and also they’ve highlighted to me, which I wouldn’t have known, is that the breaker there in the switchboard looks a bit undersized as well for that circuit.

That’s a C10 amp and that’s undersized as well so what the electrician’s done using the videos and the photos I’ve sent them has given us a quote to run a new cable. Run the new cable from the board surface mount, I would think and into the cupboard there and then and then upgrade that breaker size as well which will fix the issue.

We have given that quote to the customer and they’re more than happy. They’ve used many times so they trust us. We’re going to get that upgraded and then they’ll be back in hot water. Why the system was working for two years and then suddenly started tripping, who knows? That’s for the electricians to sort of figure out. We’ll get that sorted and they’ll be back in hot water!

Thank you for watching & I hope you enjoyed the video. Please give us a like and subscribe and we’ll catch on the next video.

Take care.

Leak Detection

Hello everyone it’s Richard at Plumbdog here.

I’m out of the property in Baldivis, Western Australia and I’m in a customer’s bathroom. He has lived here about a year and since he’s moved in he’s noticed all sorts of issues with the moisture around the shower. 

You can see behind me there’s moisture coming through somewhere behind the shower screen here sort of adjacent to the shower taps. 

The shower outlet is up there. So, about a year ago he had the shower regrouted because it was noticeably poor with the grout, so the grout guys came and sort of ripped that out and revamped it but he’s still got moisture problems. The client said he had a plumber out last week who looked at the taps and resurfaced them and just sort of put them back and couldn’t really explain too much so he’s got us out for leak detection.

The first thing I want to do is test the water meter at the water main coming in and I just want to look at the small needle on here and see if there’s any movement so I’m doing a five minute test and see if that needle moves at all.

During a test on the water meter here, I noticed that the needle is moving but it’s moving really really slowly and it’s losing about one litre every four to five minutes, so there is a leak on the main but because that’s inside and it’s just showing signs of sort of damp and moisture inside,  I’m pretty sure there’s not a litre of water lost every four to five minutes inside the house because as you can expect it’d be a swimming pool in there so there is a leak on here somewhere but I don’t think that’s it, so what I’m going to do is, I can see that the reticulation connection is just there, the master valve and the master solenoid. I’m just going to isolate them and then just re-test just to see if that makes any difference.

I’m retesting now and now I’ve isolated the retic and there’s no movement, no movement whatsoever over five minutes so we’re not losing any water which is a good sign but I was hoping to find a little bit of loss somewhere because we know that there’s signs of moisture inside so if it’s not on the water main then it’s not anywhere in the pipe work to the taps.

The next thing to do is to test from the taps to the shower rose because that’s the next place where there could be leaks so we’re going to do a pressure test but the water meters are no longer moving when nothing’s been used in the house. Behind the shower here in the bedroom cupboard you can see the plaster is really flaky directly behind the shower taps. I’m removing the shower rose so that we can get the threaded outlet there in order to test using the pressure gauge.

I’m tightening on the flexi hose to the pressure gauge there, just making it watertight in order for us to test. I opened up the taps in no particular order, a hot one first in this case. Once they’re opened and pressurised close them back up so now we’ll perform a test between the shower taps and the outlet. I’m carrying out this test over five minutes to make sure there’s no drop and in this case there is no drop so there is no leak between the taps and the shower outlet.

I’m just turning off the water main opening the taps back up and leaving them open, observing the pressure and now over five minutes we are testing all the way back from the shower rose, all the way back to the main stop tap. Again, there is no pressure loss detected so there is no leak on the main supply pipe all the way back to the meter. We’ll just open up the main again so the water’s back on. The test is completed so I remove the pressure gauge and release the pressure there,  using thread tape on the thread there and then reattaching the shower rose.

It’s important here, once it’s back on to test for leaks because if there’s any leaks guess where it’s going to go? It’s going to go behind the tiles and make the situation worse. Okay, so the silicon around the spindles there, this should have been done by the previous plumber because when the shower is in use the water can get behind those flanges and behind the tiles. I’m also spraying with soapy water to get rid of that excess silicon and wipe away and as you can see my spray bottle has seen better days – time for a new one.

So that’s my test complete. I’ve done the main test on the meter, got a pressure test on  the shower breach, and I’ve checked the taps. They were previously serviced last week. I think that plumber has actually solved the issue. I think the taps were leaking and they are quite old and I would’ve recommended replacing them so he has serviced them and put them all back together.

I do think that solved the problem but as you saw he hadn’t actually siliconed around the spindles there so with the shower in use, water would have got behind there and made the problem just as bad again. so that’s been done. Some recommendations to the client, or what I think he should do, I think they need to peel off some of that plaster get back to the brick and let it dry and it should dry before they sort of spend any more money on regrouting and what have you and then they can give us a shout if they’ve got continual problems but there’s no leaks on the water main with the retic isolated,  there’s no leaks on the pipe work between the taps and the shower rose, so that’s all good.

 

The grouting and ceiling looks good so I think he’s good to go.  I think the problem has been solved. Thank you for watching – I hope you learned something and we look forward to seeing you on the next video.

Take care guys, see you later!

Hot Water System

Is your hot water system going hot and cold and making you think there’s a fault with your hot water system? Well, watch this video first and you might be able to save yourself some time and money.

Hi everyone. It’s Richard from Plumbdog here. I’m at a property in West Perth, Western Australia. The owner is meeting me on site and she said that the tenant has reported that he thinks there’s a fault with the hot water system because the hot water goes really hot and really cold, and he can’t quite figure it out. So I’ve come out to the property. The tenant’s not home, so it just gives me a little bit of space to work out what’s going on. I’m actually in the ensuite at the moment.

I’ve got the hot water system behind us. In this case it’s an electric continuous flow system and it’s actually one of the new style ones that we recommend. It’s a Stiebel Eltron LCD version and we recommend these all the time. Strangely enough, just recently I’ve been talking to a couple of plumber mates of mine, saying that I’m yet to come across a fault on one, and then lo and behold, a couple of weeks later, there’s a potential fault right behind me.

So we’ll work out what’s going on. It makes it a little bit more interesting on this job because the tenant’s actually a plumber himself, and he hasn’t been able to figure it out yet. So the pressure’s on to work out what’s going on and get the hot water back.

The first thing i’m going to do – you want to see I’ve got my temperature probe ready to go here- is to just want to check the temperature of the system. Is it hot, cold, is it lukewarm? So I’m just going to test it on one of these basin taps just to start with. Let’s find out what we’re dealing with and then we can go from there.

All right, so turn the hot water tap on and you can see the display on the hot water system has come on. These electronics are temperature controlled, so this one’s limited at 50 degrees, but you can change the temperature. It’s on max temperature 50 here, so within a metre we should be getting 49 degrees. Let me turn that temperature program so you can see it. It’s going up there to 49.4, so I would tend to disagree that there’s no hot water. As I said, I’m yet to come across a problem with one of these systems, and because it is giving hot water at 50 degrees as it should, I’m going to go around and check all of the outlets because I’ve got a sneaking suspicion I know what might be going on.

We’re now at the kitchen sink. What do we have here? 48, so 48.6 at the kitchen sink behind me. Now I can always expect there’ll be a little bit of heat loss in the pipes between the hot water system and the outlet. The first outlet being right next to the hot water system, I would always expect it to be a little bit hotter than the kitchen sink that’s in the middle of the apartment.

Back to the system. I’ve got a secret sneaking suspicion because where people usually have an issue is in their showers. You don’t normally notice the temperature of a basin because you put your hand in for a few seconds and done. But where you always do notice it is showers, because you’re setting that to a desired temperature. If you were showering at 50 or 49 degrees, it’d be too hot, so you’d actually set that down to a temperature a little bit cooler. Usually the issue is where you’ve set the temperature but then it fluctuates. I’m pretty sure the problem is a water fluctuation problem rather than the hot water system itself, because where the hot water system is just an outlet, like the kitchen sink or the basin, it’s a constant hot temperature. So I don’t think the hot water system is the problem. I’ve got a feeling that the showers are the problem. Let’s take a further look.

Here’s the shower in the ensuite. There’s the hot water system, here’s the shower. Now I’ve got a sneaky suspicion. It’s hard to measure the temperature of this because you’ve got to sort of cup your hand and you’re not really going to be showing the fluctuation. I’m taking the shower head off the hose and you can actually see that in there is a water restrictor to save wastage of water. The problem is that they play havoc on continuous flow hot water systems, both electric and gas. That little device in there is pretty much slowing down the flow of water out of the system. When it does that below the tolerance level on the system, it’s telling the system to turn on and turn off. So when it’s time to turn on and turn off, what’s going to happen is it’s going to get hot and cold, so i’m pretty sure we just found the problem. If we just pop that little restrictor out (you guys can do this at home), let’s use a little screwdriver, pop that out. The restricted device will obviously slow down the flow of the water and now we’ve got full bore.

If we’ve got full bore water flowing through the hot water system and through the shower head, we won’t get that fluctuation anymore. Let me just put all that back together and let’s give that a try. Well, that’s hot. It’s getting a little bit too hot for my hand. Let’s try cooling it down to a desired temperature we’d shower under. That’s a nice temperature, and it seems consistent. Yeah, I think we’ve cracked it guys.

Alrighty, so job done. Still yet to find an issue on the Stiebel Eltron LCD hot water systems, but what I have found is a water restrictor issue on the shower. So next time you think you might have an issue with your hot water system and you can narrow it down to just being in the shower, then give that a try. That might save a little bit of money before you call us out. All right guys, thank you for watching. I hope you enjoyed the video – that was a nice helpful little hint for you – and we’ll catch you in the next video. Take care, goodbye.
