Had to run pipework to digital shower in loft. Had it been my job, it would probably have all been 22mm copper, since I try to work to the nth degree, but this is a budget subcontract install so I'm just trying to do it half decently.
Concerned I may have gone too far the other way, especially with clipping distances on Speedsh*t. Sadly my camera went flat so I don't have photos today.
I ran from the existing dedicated 15mm feed which came from side of CWSC in copper dropping down to loft floor, with a pulled bend to horizontal, clipped to joist. Then pushfit plastic for a couple of metres (level) with a clip every joist or similar distance, (worst was probably about 2'), rising slightly onto the pumped mixer platform. Then dead level 15mm copper with 4 pulled bends, no joints, clipped to boarding, and into pushfit pumped shower mixer isolators supplied (by manufacturer).
15mm dedicated air-free hot was much the same except that it initially rose from the airing cupboard, so the pump is the highest point.
From mixer to diverter valve, a piece of copper from supplied pushfit isolator to supplied pushfit isolator via pushfit bend supplied. Then from outlet isolators about 3' run in pushfit, clipped halfway along, and pushfit coupling into pulled copper bends clipped to bathroom wall (to be hidden behind studwork).
My main concern is that the plastic pipework might sag and end up being not level (though once the lagging is in place it may well be close to being fully supported). Could this cause an airlock problem?
Would you say this is acceptable from my desciption, or would you prefer to see... and what?
Many thanks for any contributions.
