Does PRV have to be next to megaflo

[Ben-gee]

Have a customer with a leaking prv on the cold water set for a megaflo. He wants it removing, as he has had a prv fitted on the incoming main to the house - apparently by someone from megaflo ( not sure if he’s got that right).
What I want to check is; can there just be a prv on incoming main, or does it need to be physically near to the cylinder so it’s visible. ( I can see future problems if someone turns up prv or something- leaving the megaflo dangerous.
Just the prv part would be removed, the 8bar pressure relief to remain.

No it needs to be attached and used, as it is part of the kit.

I have just spoken to heatrae sadia and they say it has to remain.
Mostly because it is set and fixed at 3bar, whereas the incoming main one is adjustable.
This is what I thought to be honest, and it just goes to reinforce "don't listen to customer b**ls**t, some will say anything to try and save money" - in this case it could end up costing them their life of house.
I just hope they don't find some numpty to do it for them.
The wife is a bit more switched on so I'll get back to her today and try and get it done before he has a chance to find anyone...

As above post, the entire kit must be used. Unless Megaflo give you it in writing of anything.
Bit of a nuisance having two pressure reducing valves as you never know if one of them is faulty.
Perhaps the valve at incoming main was put there to control all the mains cold to rest of house to keep it balanced

It's weird because I remember one of the questions on the benchmark being location of prv.

Now the cold water sets all seem to come as three separate components. His one had the prv with 3/4" female iron onto the 8bar relief. I'm going to use a female iron onto the relief and then compression for a new prv (will get reliance controls one, as this is now what megaflos are supplied with).
The heatrae sadia guy said that will keep it all up and together as they would wish, so good enough for me and keeps the cost down for customer too.

Are you G3 trained. Or Gas Safe?

 

[Ben-gee]

No Harvest, I guessed this would come up.
I do feel competent to changed this prv and then check that all the relief valves are functioning. I intend to do a manufacturers G3 this year, seems the discharge is what is mostly discussed / done wrong from what i have seen.

 

[Ben-gee]

I could pass it on to a G3 mate of mine if that is deemed necessary.

 

[Harvest Fields]

We cannot advise any more then mate. Sorry.
