Hi,
My watertank overflows in the morning, every morning,................. the pressure on the boiler is fine

Your confused? So am I. Pressurised boilers don't have water tanks so what tank is overflowing and what boiler do you have?

[Kevnbev]

I think the boiler has an over flow that goes upto the tank, does that make sence??

[plumbbob]

No, it confuses me more. Do you mean the tank is overflowing to outside or is water blowing from the boiler vent pipe into the header tank?

Really, as I don't know what tank, what overflow or which boiler, I can't help anyway.
