he should only be fitting an auto bypass valve not a gate valve, building regs, but thats not the problem it may be he has not connected all the heating returns up before joining to the primary return causing a reverse circulation through the heating. You need to find where the heat is coming...

if it was expansion it would happen only happen when boiler heats from cold and when cooling down after it has shut off, this would happen pretty much all the time

i doubt the solinoid has gone if a clicking noise is coming from it when power is applied

if he deems himself competent he CAN work on his boiler or anyone else's boiler as long as he does not do it as a profesion or get paid, it is morally wrong but thats what the gas regs say. you have to be corgi registered and have relevant ACS if you work on any gas fittings or appliances...

is the boiler the highest point in the system?

yes

has it a round or square flue, to out side?

is it a power flue or natural balanced? does the noise stop if you turn boiler stat off?

Boxster, dont use yorkshire but they are a b.....d to get couplers, tee's on, try getting one off when you have it only partly on, they need to address this, mind you they will be a thing of the past come april. __________________ Lynda Post locked to prevent hi jacking

possible air lock, you need to disconect washer machine pipes (turn water off first) the connect hot to cold using one of the hoses, then open both wm taps up and run for thirty secs turn off then check tap upstairs, repeat if nesacery.

what boiler you got and does the pipework rise from boiler or drop?

if your heating and hot water are ok, then it could be your boiler stat, or scale build up, need to know which ultimate, is it gravity hw and age

no it needs to be furthest point really or the offending basin/bath

your 3-port valve is more than likely passing, turn hot water on wait for five then see if ch port off valve is hot, you will need to hold pipe 6-12" from valve as not to confuse condutivity with valve passing, be careful the pipe may be v.hot.

sounds like you have a gas presure problem, or a flue problem, see whether you are getting flame lift with hot water running
