Replacing combi boiler.

[dave1971]

I'm replacing our gas Central heating boiler(ferroli) with a new combi boiler(baxi). Dont worry, I'm having a gas safe engineer do the connecting up.
My problem is that i think there is a small leak on the system as when the boiler is off, during the course of the night, the boiler loses pressure then fails to error mode. So i have to top up with water and reset. Its not a great amount of water. So can anyone recommend a good pour in sealer to sort this problem?

A good pour in leak sealer is an oxy moron.

Very good. Might just try an egg white, used to work on my old metro

Gif your getting a new boiler just pay the bloke to find the leak and get the job done properly.

When we read that we immediately think that the engineer is not going to be doing the full and proper job which would include identifying and correcting any leaks.

Putting chemical to stop leaks in the system is likely to interfere with the proper cleaning and protection of the system.

Starting to regret asking now. Was only looking for suggestions to save me ripping up solid oak flooring and then the floorboards etc.

Why is it when people don't get the answer they think they want, they get in a huff.


If your car needed a new engine and one of the mounts was broken, would you be happy to use a bit of bluetack to fix it before fitting the new one?

Ah blu tack. I'll try that.
Thanks for being helpful.

Chances are if you have a Ferroli the leak is on the boiler.


I would also suggest an attitude check.

Is that an attitude check 'valve' Dan

Useful to get you limping through the winter but it's hit and miss!
Don't think I'd want it lining the inside of a brand new HX though!
Try it, by all means but it's your call!

Pour in leak sealers will reduce the life of components in your system, and may affect the safe operation of pressure relief valves. Once the old boiler is isolated from the system, pressurise the system and see whether you get a drop. As Dan has said, it might well be that the old boiler is leaking

Apparently Dave you're 45 years old but still need to grow up a little
