Fitting Extra Valves

To save time and water when draining pipes for minor repairs and servicing, install extra valves to divide the system into sections or to isolate individual fittings and appliances.

Step 1

Fit gate valves on the cold feed pipes from the storage cistern. This will save you having to drain the stored water when servicing the low pressure side of the system. If you fit a second stopcock on the in-feed pipe, you can drain the cistern without turning off the rising main.

Step 2

Fit isolator valves in the supply pipes to taps and appliances. This will enable you to isolate the individual fitting for servicing.
