Pressure drop in Vaillant ecoFit Pure 825- 835

[sofie]

Thank you ladies and gentlemen you have all been very helpful.
The discharge pipe has water dripping out and for some time it seems (if I'm not wrong) as there was also some sludge. It seems the engineer that came to service did not check this.
How can I go about this with or without the engineer?

You need an engineer to change the pressure relief valve , preferably not the jerk who attended previously!

 

[Harry Bloomfield]

It doesn't.
You a plumber? Don't recall you are/were!

I would suggest, that you crank your neck in..

 

[sofie]

Think you misunderstood.

The boiler has a pipe that goes to outside and is an open ended pipe... This is your discharge pipe and allows the system to "dump" water to outside in the event of going above @3bar in system pressure.

Look for a pipe that comes out the wall and bends round or down to point back at wall or down it.

Thank you very much for clarifying that. I tried really hard to Google it but couldn't get a clear description. Not to mention my lack of knowledge in the subject.

In the visit 2 weeks ago it states that he changed the PRV. Could it be anything else? Or could it be that he didn't actually change it?
I wasn't there during the visit.

Anyone's guess as to what was , or wasn't done. If water is leaking out of the pipework outside now the prv needs attention.

You suggest a lot of shit so no change there then xx

 

[Harry Bloomfield]

You suggest a lot of **** so no change there then xx

As said, crank your neck back in. Your comments are completely pointless, and unnecessary.

I don't want to malign the fellow, but when you call them back, explain that the PRV was replaced and dumping water. He may well have replaced a faulty PRV with a faulty PRV. On the balance of probability, it seems unlikely that both PRVs would be faulty, but, yeah, it could happen.

And a sandwich bag, tied over the outlet, full of water would absolutely confirm it!

I get what you are saying but I respect both of you and I am therefore ducking out of this one. xxx to you both (both of you have helped me in the past).

As are yours.

As are yours.

Guess it must be something in the air, at Potters Bar then..

You either have a leak on your system or an internal leak in the boiler's main heat exchanger. It can be tested by turning the boiler off and using the isolation valves to shut it off from the system. If the boiler pressure drops with the valves closed, it's a leak in the boiler. If it stays steady then it's a leak on the system.

You're a little confused about your model number, incidentally. Ecofit Pure are either 25, 30, or 35. 825 and 835 are ecoTEC Plus models. And it's only one of them, it can't be both an 825 and an 835, that's two different boilers

I'm afraid she's right and you are wrong. This is what came with my EcoFit Pure 825
