I'm replacing a bath, basin and WC, with associated taps. Hot water originally came via an immersion heater (cold via a roof tank), but this was changed a few years ago to come via a Combi boiler (cold via direct feed).
Neither bath nor basin has any service valves, but the bath/shower mixer has a check valve on just the cold. The new bath tap is a simple replacement (two hole mixer plus shower), but the basin tap is a one hole joy stick (combined hot&cold).
I was planning on putting service taps on all taps feeds, but do I need to add check valves too (as one guide suggests)? And what about the WC?
I believe there are check valves immediately after the main stop tap and associated with the combi boiler (but could check).
Any advice would be very welcome.
