In a big mess, dont know what to do please help! :(

[Mr Smyth]

I may be being simplistic but has anyone checked the PRV?

Their will be a pipe coming out from the bottom of your boiler which will go straight out, through the wall to the outside. Check there isnt water dripping from it.

Before the boiler installation the plumbers did a chemical flush

Your installers should have had you sign something like this before starting........

and then you wouldn't be so eager to slander them or litigate.

Yes I've checked that already and there's no water dripping from it however there is another pipe connected to drain so it could be leaking from there but I highly doubt that.

I didnt know the flushing would create a leak. Also i didnt sign anything like this. I dont really care about litigating the company at the moment. But if its gonna cost me thousands of pounds to fix that i may have to.

As a customer i expect to be told all the risks and benifits of the work being carried out BEFORE it is actually carried out.

It sounds like the installers have been quite straightforward with you.

I ask customers wishing to renew combi boilers about the prior history of pressure dropping, because if this has been a problem I need to tell them that the basic quote isn't going to cover dismantling the house to find a pre-existing latent defect. (Lifting laminate floor is time consuming and replacing it is a nightmare, and costing this is difficult, especially when the leak could be anywhere).

In this scenario you paint the installer in a bad light but they have answered the phone over the holiday period and explained the situation.

The only way you could expect them to have any responsibility for your leak is if you had specifically informed them of the problem at the quotation stage, and asked them to rectify it as part of their offer.

As things stand, your new boiler will last as long as the Hermann if you don't get the water loss issue fixed. Vaillant will cancel your 5 yr cover if they find the boiler full of sludge, which they will, if you keep refilling the radiators with fresh, oxygen and mineral rich, water.

check all the new valves that were fitted with tissue paper for damp,check the condense line is not running with the heating off,check the safety release is not dripping outside,after that its floor up time.

The radiator with the new valve is fine but the one in upstairs bedroom had problems in the past and was leaking. A plumber came and fixed it but before that we had to wrap a dry cloth along it and change it every 2 days or so as it would get wet.

Now i just wrapped a tissue on top of the valve and only the quarter of the tissue is wet and then the valve was dry so im guessing very minor leak from the valve, but it couldnt be the problem for pressure dropping to zero from the recommended level in a day ?

They havent been straight forward with me as there wasnt a pressure dropping prior to the replacement ? If there was obviously i would tell them and try to rectify it.

Ive already filled the boiler about 6 7 times within past 4 days ..is that going to kill it ? : /

Make sure you are following the filling procedure correctly.

These boilers are not exactly plug and play.

This is to ensure that the heat ex. and the pump are purged.

When you have located and fixed the leak get some inhibitor in the system.

Already have the inhibitor in the system while replacing the boiler. And while filling the system do i have to turn the boiler off or something ?

 

[landyandy]

The filling procedure is in your manufacturers instructions.

Not following the procedure each time you fill could give you problems.

Your installers didn't create the leak. (If there is indeed one)
Dodgy pipework and joints creates leaks and by the sounds of it your installers have not fitted any of those.
Chances are that it would have manifested itself anyway without the installers intervention sooner or later.

Pulga seemed to have found his leak with a rather unconventional method. You could try this.

I've never tried it so cannot comment.

I would try it but im not on that level yet. I have no clue how to add another type of fluid in the system.

 

[Corgigrouch]

If you are filling it that often, I wold be looking for a pretty big leak.... Short term refilling your boiler is fine but you will need to get the leak fixed ASAP and then have it replenished with inhibitor as it is being diluted everytime you top up.

I think that your installers have been fair with you.

Herman , can't remember what happened to them , bought out by some one or ???

Was not the original system already sealed up eg on the herman ??

Internal leak sealer ?? well it can work I have used it with success a few times , but than again I have used it & it went pear shaped , blocked or restricted the heat exc on a J&S Reno , which I beleive probably use's the same heat exc as a vaillant ??
So you take a chance when u use it ???

well then i think in that case im better off not using it. My only concern is if theres a leak why doesnt it leak even when the central heating is not on ? ..the pressure only goes down after the central heating is used and the radiators arre hot
