Thanks for the credit Jimbob! This install was one of my best installs! Didn’t take me long either!! And I had to put towel rails on separate system as all great plumbers do!
Haha! Top man! You local then?

“Here’s the boiler..”
Shows you the cylinder cupboard..
🤣
Standard!
Boom! And that’s all my issues addressed in one short video!
One of the nicest houses I've ever seen. Jealousy is ripping out of me
That really good it’s the first time I have seen it .
Thanks

Loved the bit when you mentioned the beer, I nearly wet myself lol.
You’re the man!! Brilliant explanation 👍👍👍
Very nice little video enjoyed this one 👍👍👍👍
Brilliant 👏 . I have a problem with a sunvic 2 port valve .the valve itself is OK but the metal electric box is broken but can't seem to find any sunvics on sale anymore .was wondering if you knew which motorised valve part you could get from amazon that would suit an older 5 year old sunvic thanks in advance
Great video chap 👍😊
The balancing rad valves are the coarse adjuster and the thermostatic valves the fine, good vid!
I used to put a Balloon over the PRV Pipe outside and check it in a couple of days ! 😇
That’s quite a good idea!
Those Danfoss ZV are horrendous for leaking, especially if the expansion vessel has depleted and the pressure exceeds 3 bar!
The white expansion vessel is for the portable water side of the system but I didn't see the heating system expansion vessel, which is normally red. Also how is the heating water heated? Is that an electric or heatpumped system? He might still have a flat or broken expansion vessel causing the loss of water and thus pressure. Lovely house though and great visuals in the video.
Hi James
Why do you need a separate Loope for towl rads?
And could you do a video on it in the future please
Thanks
Mark B
It’s quite common in new builds to have the towel rads tee off on the primary flow and return so when the cylinder gets heated up, the towel rails come on too, in preparation for showers/dry towels etc.
@@kurtthedrummingplumber so they are not under the control of the thermostats? So they heat up in the summer??
@@oninbridders exactly. Alternatively, the can be installed dual fuel.
Where was the expansion vessel for heating?? I had similar issue on a job before Christmas all safety features done on hot water side but no prv or vessel for heating side, could have been boxed in somewhere but no way I was taking a chance as I couldn't find either and customer didn't know.
I think you're BRILLIANT

Knock on the expansion tank. If it rings like a bell, it’s good. If it’s dull, it’s full of water and bad. Even if that was the potable water expansion tank. 😜
Gas Engineer here - got my daily fix of boiler porn thank you!! 🤟👌
If Carlsberg made plumbers
To check pressure vessels just give a wee blast (half a second) of the valve at the top with a screwdriver or similar - if its air that comes out its probably fine.
so not true.need to drain off pressure of water and check air pressure on diaphram
@@markdurrant1366 if the diaphragm has burst the air will make its way into the system and water will come out of the top valve
Once again can happen. But normally diaphragm may have lost pressure. Maybe be down to .1bar. you still get air from Schroeder valve but huge system expansion when hot. So diaphragm needs to be recharged if req.
Why would they need to install rads and towel rails on separate loop? What are the benefits for this?
I guess it means they can have towel rails on in the summer without having to turn each radiator off. That’s about it.
I would have moved that towel from the towel rail rad in the bathroom or you be buying not just a filler loop valve but a new set of towels
Expansion vessel in my house is always a pain in the arse!
Save a second phone call may be check and if needed re pressure the expansion vessel.
Press the schrader valve Down and see if you get any water out , don’t be lazy. 😉
Gorgeous house. What does Dave do for a living?

You’re having me on 😂. It was a serious question because I don’t have a house like that and I want to know where I went wrong. 😁
@@gareththomas1395Watching You Tube rather than grafting?
@@normanboyes4983 ah but grafting at WHAT? Graft all you like in a shit job but he did something different.
Won't be the expansion vessel for the unvented cylinder seperate systems white for hot water red for heating
I live in a bungalow and recently drained the system, it’s gravity fed and all the air is out of the radiators. We have filled the system but can’t get all the radiators back to what they were. Any helpful suggestions?
Probably airlocked the system and blocked your cold feed
I also have a gravity system in a bungalow. I'm a DIYer, not an expert plumber (hence why I love this channel), but I know every inch of my system now. When I do a refill I start at the top (loft) and bleed the two top spurs of pipe (don't know the technical name) that protrude from a tee on the outward and return main runs of pipe. I then go back downstairs and work my way around the radiators with a bleed key and rag. Because these are all on the same level I don't believe the sequence matters - I haven't been able to discern a pattern anyway. The air wants to go upwards, not sideways, so it doesn't matter if I start on the furthest away or nearest to the boiler (solid fuel Rayburn). It's just a game of splat the rat, or vent the bubble. If everything else is fine then eventually the air loses the fight and the radiators get hot.
One thing to watch is if the radiators don't get hot and the boiler overheats; rare, but can happen. I had this earlier this year and it took me far too long (I'm not a plumber) to realise a piece of insulation had found its way into the old open-top heating expansion tank (which had an insulated lid) and blocked the exit pipe, preventing the boiler being topped up. Sounds simple and silly I know, but I'd drained and refilled the system and thought I'd done something catastrophic; the small sodden piece of fibreglass that had been lying at the bottom of the tank for probably years was sucked onto the exit hole when the system drained and I didn't discover it until the refill and relight. I've now ripped out all the old plumbing and refitted with brand new closed-lid tanks and some better pipe routing. And a new Wilo pump.
Assuming you've got heat in the radiators you then need to rebalance the system; stay with the Plumberparts channel and look for the video 'How to Balance Heating System Radiators - Plumbing Tips'. You'll need some pliers/grips and some patience, but by adjusting the stoplock valve (the one with the small plastic hood) you can get the right amount of heat you need for each room. Also make sure you have a modulating central heating pump by the way, which reduces the pumping pressure as it detects a thermostatic control valve (TRV) on a radiator close; that will save you some pennies on your electricity bill.
Anyway, best of luck.
@@ateleskier7066 Thank you for replying. I have heat going to half the radiators, and very minimal to the rest. Very frustrating
Come on, you know that’s the potable water expansion vessel!
Yeahhhh! Brain fart!
No problem with that, you can use potable water vessels on heating systems, just not the other way around.
When ur whole house fits in someones hallway 😢
I had similar issue, when moving into my new house the gas boiler internal expansion vessel was leaking. The plumber came out recommended that i just disconnect old one and he will install external one. The reason he did that is because the gas boiler is over 25 years and they don't make parts for it anymore. He installed the expansion vessel and left. I started to notice the system losing pressure and the plumber would tell me to refill the system. The plumber couldn't figure out why the system was losing pressure and it costing me money from the plumber changing parts that he thought was causing the issue.. I got sick of guy as he was costing me money. so I rang another plumber. The plumber asked me for make and model. Then wanted to know what last plumber did. He came to house asked me to show him where the expansion vessel was installed. He checked it out he told me the last plumber installed oversize expansion vessel for the system so the diaphragm wasn't moving at all to allow hot water in so the water just flowing out through the safety valve outside. He fixed the issue and spent 10 mins in the house to make sure that everything was good and also service the boiler. It just goes to show some people don't know what the hell they doing and costing people money.
Is it possble you just had a leaking PRV which may not have closed after being opened by an over pressure event? (cause by debris and dirt in the system) I would be interested in the physics behind the idea that an expansion vessel was too big. It might be fitted in the wrong place, flat or too small. Never heard of "too big" as a problem though. I believe plumberparts has a video on how to clean a PRV but it is, usually, just as fast to replace them as they are quite cheap.
Why not just whack the towel rails on before the zone valves? No need to overcomplicate it. Also just check the expansion vessel pressure
I didn't install this system. Sometimes peeps just want the control I guess?
@@plumberparts Sorry was just meaning in general not aimed at you i realised you didn’t install it.
That is what I always specified. You get max flow temp in the towel rails whenever the boiler is running. Set the TRVs on the high side to suit and then the bathrooms are always hot and dry. Same setup in utility rooms where they have two rails rather than a rad.
You could play a football match in that house
You should really be checking the water quality to see if it needs inhibitor. Also you should have checked the expansion vessel pressure. Good content but poor service
Ha! Thanks Adam! 😂 I did buy him a kebab afterwards. Plus I didn’t charge him! 💀
Geez, these heating systems looks so complicated, to many mechanical valves, thermostats, switches, bypass this bypass that, flow control OMG I can see how trying to diagnose a fault could easily become a nightmare.

You look very short next to that guy
5:52 - that’s the hot water expansion vessel not the heating one… amateur
