Combi boiler and fitting isolation valves

May 11, 2005 4 Replies

I have a Worcester Bosch 26/32 oil combi boiler. I need to fit isolatio



valves on the hot and cold supplies to the kitchen. My problem is how t do this. Is it simply a case of turning off the water at the main inlet stopcock and draining the hot and cold pipes, fit the valves, an then turn on mains again to refill the boiler? Thanks for any help

Yep, that's basically it.

But you should not need to drain or refill the boiler's primary circuit that's just unnecessary extra work.

Can you please tell me how I avoid the boiler's primary circuit fro darining down when I run off the water from the kitchen taps befor cutting the pipes

If you not sure how to then you probably won't :-)

The primary circuit is the one that circulates the water around the heating system. This is separate from the mains fed direct hot water (though normally filled from the mains). So running off the water from the taps won't drain down the heating system.

Just do as you intended and you will be fine.
