For the sake of convenience, I'd like to use just one isolator for both a sink and a toilet in a bathroom. This isolator will be under the sink, but the toilet it also controls will be at the other end of the room.
ot: I see in a few central heating installations there are stickers saying words to the effect "disconnect filling loop after use". But they are they ever?
ott: How to disconnect a CH filling loop. Is that long valve thing on the feed to the CH system a non-return valve (Hence the wings on it)? I don't want to undo one and see the contents flooding out!
What rules there are for plumbing don't usually cover useful stuff like usability and maintainability. (typically they are just protecting the cleanliness of the supply, and attempting to impose energy efficiency on you).
Except that the Water Supply (Water Fittings) Regulations require pipework under concrete or solid floors etc. to be sleeved "to ensure that the pipework is accessible and/or can be removed for maintenance or repair."
I take back some of what I said above then - they seem to have expanded the scope of the WRAS regulations since last I looked. (although admittedly I was thinking more about building regs rather than WRAS previously)
This one caught my eye:
Q. CAN A PUMP BE INSTALLED ON A SUPPLY PIPE TO BOOST LOW PRESSURE?
A. Yes - Pumps are allowed to be installed on supply pipes. However if the pump is capable of delivering more than 12 litres per minute, you must notify your water supplier and seek their consent before starting any work. Notification Page >>
