question on water pressure in combi

[Dotty]

oh I thought commercial meant bigger pressures and stop checking out my rear

..... When you stop talking out of it......

1 Bar is fine, unless you own a 3 level house then 1.5 bar is fine

I useto use around 1/2 bar per floor

the amount of people that pump them up and up to try and increase there water pressure , lol

or over 3 bar then wonder why it goes to zero

the prvs never seem to reseal once they go , pumped a few expansion vessels up in my time but normally end up replacing them

did have a boiler that kept dropping and instead of replacing the faulty internal expansion vessel they had fitted another one in the loft ,

What should it be then if the boiler is on the top floor of this 3 level house then?

 

[oil gasman]

I would normally fill them up until I got water out of the highest point , as u only want to get the water to the top of the house , also due to low water pressure cut out switches I would normally put them around 1.5 bar ,

hopefully this is right , lol

hopefully this is right , lol

looks like hope has abandoned you.....
