your valve body may have seized, with the actuator removed try operating the valve spindle with your thumb and finger.

between £50 and £70 pound, but if its not leaking then you wont need it replacing, have you checked your radiator valves? if it only needs repressurising every 2 months then it will only be a small leak.

you have an automatic air vent so not to worry, can you see a pressure gauge anywhere?

Fact. the ceiling would have colapsed by now if he is losing that amount of water, maybe coincidence that the pressure dropped when the carpet was laid or maybe not.

presure relief valve passing, check for signs of water coming from pressure relief pipe outside. small leak from a rad valve!

double check your wiring, you may have the demand and common the wrong way round at the cylinder stat.

its hard to describe because they vary, can you see a brass fitting with a nipple on the end? if not try bleeding an upstairs rad, you want to check if its sucking in air or releasing air or water![/img]

you could have a blocked cold feed, (not enough water in the system), do you have any manual vents in the airing cupboard (thumb vents)??

also as long as the old washers havent split try flipping them over first, usually does the trick!!

1/2 " tap washers, but it sounds like the jumper has come off the thread on the kitchen tap caused by overtightening the tap when turning off.

possibly a blocked heat exchanger, was a service agent for ideal for 3years, came across this fault more than 50 times, heat exchangers changed under warranty.

is your existing clock twin channel? (htg and dhw). or single channel?

did the water board tell you what pressure your main was running at?

if you have existing pipework buried under a concrete floor that is more than likely where your leak will be, probably a weak soldered joint leaking due to the increase in pressure with the new system i.e conventional system (f and e tank) to pressurised sealed system. as Agile said i would...

hi, when you initially turn on a tap does the water flow quite fast but slows down after a few seconds?
