Hi, I have an odd problem...I moved an outside tap and I shut the mains stopcock off. When I opened the existing outside tap hot water came though but it wasn't under much pressure and didn't last for long.
There is no double check valve on the cold water feed to the
boiler, the manufacturer's instructions show that this should be
installed before the filling loop. Could this have anything to do with the problem and what is the purpose of this check valve?
Does the brass fitting at the end of the cold feed to the boiler (ie-
that goes into the boiler) incorporate a check valve?
As the original installer didn't put in a dcv how bad is this?
Also when the outside tap is being used you cannot fill the boiler and
also the shower doesn't work. The property has quite low pressure
water but is there any kind of equalising valve that should be
installed and where should it be installed?
When I arrived at the property they also said that the loft radiators
weren 't working. I bled the radiators for a few minutes (!!!!) and
everything ok. Could this be linked to the same problem?
Hope this makes sense and thankyou for any help
I am currently doing a gas course at MET-UK so am still at a learning
stage. I am looking for a full time placement (free!) from 30/11/09 in
Derbyshire, Nottinghamshire., Staffordshire or Leicestershire.
