Trying to take loops off the pump outlets and running
them for metres under the floor before lifting to the mixer is not a great
idea.


I've never found this to be a problem. The Watermill pumps are designed to
be mounted with the I/Ps and O/Ps at the top of the pump. The flow valve is
in the output side and gravity operated, which is why they specify the
outputs as requiring an upward flow. There is no problem to taking the
output feeds upwards, then through a loop to below the floor. If this is
the standard push fit flexible hose connections, the only problem is that
the hoses are too short and stiff to bend through a 180 degree loop. You
would need to add a couple of 90degree elbows to achieve the loop back. It's
worth considering adding some full bore stop valves adjacent to the pump,
the flow valves are IME not long lived (5yrs?) and it makes replacing them
much easier. Distance is also not a problem, I've some feeds which are 30M
with no problems ( apart from the pressure being too high for the shower
head connections, which leads to washing the ceiling!) Hope this helps.
