I just had the same problem on my greenstar 30si. I wonder why they don't just sell the top hat rubber seal as a replacement instead of the whole valve, what a waste. I my case I turned the top hat seal inside out so the rubber was undamaged and pitted and reinstalled it and it worked a treat.
Great stuff ! Was quite incredible the amount of these that were often replaced on a firm I used to work for without trying this way first. I think some engineers wouldn’t even reseat a tap and just change it lol ! Even worse when the valve is replaced and the vesell isn’t even checked so of course back to square one again ! Rant over lol
I have been to Greenstar Juniors that have come off the wall for the PRV and no one bothered to pump up the vessel... I could tell because it still had dust on the cap.
I try and start from scratch every job I walk in to and find it helps.
HeatingGeek lol ! yes some people do make hard work for themselves. With more knowledge the jobs become a lot easier through experience. Get part 2 up on the other video we are waiting lol
Its up. Part 3 should be filmed/done today.
great video i never thought about doing a prv still attached until now, in this game we learn something new everyday...... keep up the good work mate
Everydays a school day as they say. Thanks for watching. :-)
Hi I've changed the diverter valve. I ended up draining from the release valve. Now it is dripping outside. Do I need to air the vessel? Or can I just clean the valve and would that be ok? Please help as I'm unsure
when you say pump the vessel what do you mean? I just cleaned my prv then filled the water pressure back up to 1 bar. It all seemed ok, for about 10 mins then dumped a lot of water? I didn't have any silicon grease maybe that would help?
Every time I drain a boiler I pump up the expansion vessel. Otherwise what just happened to you would happen. Every time I drain I pump them up
Spot on, exactly how it should be done.
Thanks ;-)
Very good detailed videos, keep them coming
Im trying
Recently used a tap re-seating tool to grind out a pitted TPR valve on a unvented cylinder as replacement was on a 7 day wait so got them out of trouble until then
I would of thought it wouldn't seat properly, as the plastic cap has a flange which stops it tightening down any further.
If you get what I mean.
HeatingGeek was an old Gledhill & worked a treat
@@charliesebbage9401 Just a light touch up I guess?? Not grinding 2mm off?
HeatingGeek definitely not 2mm! Enough to smooth out the pitting
@@charliesebbage9401 Yeah I thought you just gave it a tickle.
Really hard t get to mine, right at the back and it is constantly pouring out
Worcester Bosch 542i any advice would be great as can’t have the heating on
Get someone to fix it. Where are you based? We do a fixed price repair.
Well I can do it myself bud as it’s a push fit kind just a bit fiddly
Hi, can I ask why you need to add silicone grease to the prv? Thanks and great video.
When rubber parts are slightly pitted it helps them seal.:-)
@@HeatingGeek thank you, most appreciated
@@howardelvidge4436 No problem. :-)
PRV's are not expensive so why muck about dismantling and cleaning? Just replace it, the CUSTOMER would have greater peace of mind with a replacement rather than a
'refurb'?
I wonder whether a tap re seater would thread into that. I'm thinking probably. ..
No you don't want to recut it as it would be looser after. Less pressure to open!!
Nice work.
Thanks :-)
Nice one mate
Thanks :-)
Fair point!
A PRV is a safety device the clue is in the name PRESSURE RELIEF as an engineer when a customer calls someone out they are expecting a one times fix not to play around very often the prv is corroded and there are causes for failure that should be checked when replacing it. They don't usually cost a packet under £20. Please don't cluck around with these valves don't be a penny pinching thicki. Also if you haven't a clue what your doing you will enviably wind up doing the job twice. Putting silicone grease around seat is daft it will warm up squeeze out job to do again. There is a sneeky way you can save money get the GC number give that to the engineer and there may be a chance he will get the right part or parts.
The mind boggles with these so called experts on UA-cam, you can pick up prv parts for next to nothing, at least you talk some sense 👍
👍
thanks ;-)
I bet you charge parts and 3 hours labour for this while you're dipping your KitKat in your tea from the grateful pensioner you're ripping off? Thanks for the vid, I can now do that myself rather than getting some scamming wanker tradie in to do it :D Wanker.
You cheeky bar steward 🤣
You sir, are a funny guy. I do fixed price repair, so pensioners and cnuts like you pay the same. :-) You are sooo welcome.
