worcester 24si ll gas pressure?

[1iydwilly]

hi im working on a worcester 24sii ll non condensing combi boiler...the water is coming out luke warm and the more i open the tap the colder it gets..i suspect that the gas pressure is low i checked the working pressure at the meter and thats ok 21 bar....but when i check the inlet pressure at the gas valve i get nothing?? the same at the burner pressure test point!! the boiler is firing up fine and the heating is working but the hot water just wont get hot enough...has anyone had this problem& could someone confirm its the gas valve or maybe something i missing...thanks...

have you opened the inlet test point on the gas vlv? have you water in the gauge?

possible filter on the gas vlv blocked with black dust from the gas mains

Or do the outlets have those screws that have to come right out to open them, like on a meter test point?

He definately wont have any water in his manometer with a working pressure of 21bar.
