Why not ask your plumber to explain it to you.

What about the prv? and also checking that boiler as a high limit.

 

[Ray Stafford]

Yes, its perfectly possible.

And I don't mean to sound rude, but why are you letting him work in your house if you don't trust him to do a good job?

what boiler do you have

I trained as a plumber for abit but didnt carry on with it and i hadent heard that you can change from vented to unvented, is it just a case of chopping the cold feed to the F&E and linking it to the flow from the F&E? iv got a Valient

thank you

and they say a litle knowledge isn't dangerous.

Ask your plumber to take you through it.

It's entirely possible, and he's confused you by using the term unvented in relation to your heating when he should have said he'll convert it to a sealed system.

There's nothing the untrained eye could pick up to check he's doing a good job, so unless it looks a right pigs ear, just let him get on with it. Show some trust brother!

Thank You for your help everyone, 1 more question do i or he need to inform building control or any1 that im having a megaflow fitted???

 

[SimonG]

Have you asked him if he is g3 qualified and a member of a competent person scheme?

Thank You for your help everyone, 1 more question do i or he need to inform building control or any1 that im having a megaflow fitted???

If he's G3 he will self certify the install, if he ain't he should not be doing it in the first place!
you don't seem to have much trust in him? Strange to doubt when you are spending Megaflo money?

 

[JoeRead]

No i havent?? because i know a little about plumbing i got chatting to him and hes Level and NVQ 2 qualified. whats g3??

 

[JoeRead]

Is it against the law for some1 whoes only NVQ Level 2 qualified to install a megaflow??

Yes, unless they have trained for unvented specifically. He should have a bpec or similar card with the unvented qualification.

 

[JoeRead]

Now you can see why i got worried. He said hes done loads before as hes been doing it for years so i trusted him. Will he need to inform building control?

 

[vern]

Yes, unless they have trained for unvented specifically. He should have a bpec or similar card with the unvented qualification.

Yep unvented qualification is known as G3.....I will do it for £3K if you supply the Megaflo.......no seriously do your homework, get someone in who is qualified!

 

[JoeRead]

Thank You, ill have 2 have a word with him and see if he can produce any certificates of Plumbing

G3 because it is Part G of the building regs & section 3 for hot water systems, now have a look at the link it explains all.

Make sure you pay him the correct rate for the job he is doing,and make sure its cash,and make sure he follows you to the bank to see you draw the money out before you pay him....you carnt be too safe these days..lots of "dodgey" "stuff" going on.
Failing that contact megaflow and they will fit it for you, then you can sleep at night.:fuk2:
