This method of getting a PRV out on a Worcester works better when the boiler has been rear piped as you don't have as much room as when it's piped down.
Easiest way I found is to just remove the pump and try to flick it out with a flathead, and then lever the new one back in.
Nice one. What a horrible design for the engineer. And you only had one hand while filming, your a giant. Thanks a lot and keep safe you and yours.
Haha thanks mate!
Well done mate, great video on how bad those prvs can be to change
Thank you mate 👍🏽
Good job! I know your pain! most of the time i open the the bleed valve at the top of the heat exchanger to get nearly all the water out, also use it to vent the heat exchanger of air when refill it .
Thankyou great explanation, hardest part is getting the clip back in
Yup!
Good job takes about 45 mins to do ...sometimes easier to leave pressure gauge in
CP you seem to have missed the most important tool......a bloody big hammer.
That looked a total nightmare lol ....but you always prevail 👏👏👏
It really was mate but where there's a will there's a way!
Manchester
Nice work mate its a very difficult job but you done it with ease good man
Thank you mate, it does get stressful on site but sometimes you just need to take a 5min break and crack on again
@@cputilitysolutions break sounds good to me to refresh and come back stronger 👍🏼
Honestly I look up to you, well done man, but I just usually put an external prv on the boiler, that's too much hassle.
Lol thats not allowed by Worcester. Not In the Mi's
Ive tried loads of ways to do this. in the end i think the most straightforward is just to drop the boiler off. Three screws to disconnect the flue turret and wiggle the grey plastic flue piece down inside. The electrics are on plugs so take a couple of minutes at most to disconnect. Then trap out, undo the nuts for the water and gas and its off the wall. Probably 30 mins max to drain it and whip it off the jig, the the prv takes about two mins to change then. In another thirty mins its reconnected and filled. In and out in an hour. Ive wasted 30mins just trying to get the stupid PRV to pop out after removing the cold supply and still had to take it off the wall in the end. The off the wall method is predictable and apart from a few fibre washers doesnt require any o ring changes. Worcesters are dog s@@T. Always have been.Always will be. Designed by clowns for clowns. The new ones arent any better. Have you seen the joke of trying to do a simple elecrode change on a cdi compact. jokers.
Cheers mate, yeah I've had to take it off the wall a few times as well. The new CDI compacts are the worst, I've done a video on a full service on those too, the electrodes are a joke!
I always have my wet and dry cleaner plugged in ready to go when I repair any boiler, those sudden rushes of water can get into the pcb then you have to waste time trying to get every drip of water off the board before you power up. Really bad design, I don't get involved with repairing the prv's if I can help it, the new seal kits come in a large bag, about £40 and you only need a few of them, got loads of them now including the clips.
Thanks mate for sharing nice one
Do you need to change the prv everytime it passes ? Like if it’s say the expansion vessel would you still change the prv
Yes mate because most likely dirt will have gotten into the rubber boot and it will continue to let by most likely. Better to be safe than sorry 👍🏽
I changed one and I'm not a plumber same way putting that clip back a pain big pliers the key
I stopped fitting them 10 years ago for this reason, it’s not fair on the customer to continue installing them once you know of this design which creates a huge expense.
I've never fitted a Worcester yet, only done repairs on them
I dont install Worcester bcoz of this hassle, to complicated and huge expenses for replace parts compare with baxi ,vaillant 😅
I came here as my PRV is broken and my boiler is boxed in a cupboard above a bath nd the pipe work tiles in underneath with the electrics and there is no rom for an orange bucket. .... . I am going to cry . LOL
Brilliant job as always mate, did you changed all the rings? Or did you reuse them all?👌
Thank you mate. Nope reused them all as they don't come with the PRV unfortunately
Cool vid... but why would you not protect the worktop and sink?
How much should you charge for this?
Hi pal , i think I have the same issue but on mine the pressure keeps on dropping. anyways how much would that job cost ??? please advise
Hi, every engineer would have their own prices but would need to come and take a look first to assess the job. Whereabouts are you based?
Way easier to take boiler of wall, sounds like a big job but it’s pretty simple.
Yes just flue to deal with
Any idea s got a strange bang now and then only on heating side Bosch worcester 30si greenstar all been serviced burner cleaner out heatplate cleaner out no airlock s strange seams to start bangs go s off and starts ok any idea s thanks
Difficult to say without seeing it or being there when it happens. Best thing is to try and take a video of it when it happens if it's intermittent and get a gas engineer round to take a look again 👍🏽
@@cputilitysolutions thank been serviced last year had every thing two manifolds air vent new fan heatplate cleaned out burner cleaned out new electrodes had £1000 spent on it new baffles works all ok just a bang now and then thanks any way 😉
did u not pump the vessel whilst draining theres alot of water that come out
I did but there's always residual water left in the pump when you take it off
Shit fucking design....like everything else about Greenstars.
Luckily they're fairly reliable but awful to work on.
All manifolds are plastic and crack
where are you based need a WB boiler looking at in Warwickshire
I'm in Essex I'm afraid
Once you have done one you realise there are no shortcuts , nightmare , you can change a baxi prv in 5mins not 5 hrs.
Real
That was a nightmare. Not very engineer friendly. The instructions should suggest not to fit that float to wall.😂❤
Yeah can be a pain
shit design, over complicated, out of date, would not fir Bosch if it was free! i usually put a straigh pr valve on the outlet. easier to take the whole thing of the wall.
Agreed! Unfortunately I'm helping out a mate to fit one next week...never thought I'd see the day! 😂
A horrible job to have to do.. thank Worcester for that!! Well done tho
I don't mind when they're piped up normally but the rear piped ones are a ballache!
That looked painful 😣
What a crappy prv design by worcester...
Reason alone to avoid boiler
Yup but a good earner when most will turn it down
Sorry close not float
Well done! Terrible design. Main reason I won’t touch a WB as a self employed engineer
Worst prv know to man the designer needs sacking
💯
Another reason why Worcester boilers are overrated, wonder if the new ones are just as bad
Good money makers on repairs though 😉
Wat a fekin hassle for a prv 🤦♂️😂
