Pipe sizing
Long pipe runs, on both inlet and outlet, will reduce the flow rate at the shower head. 22mm pipe work should be
used on the inlets and reduce down to 15mm as close to the valve as possible to reduce pressure losses and help
maintain flow rate. If using 15mm then copper pipe is preferred, and minimise the number of elbows used.
If long pipe runs are unavoidable on the outlet, use copper pipe rather than plastic, particularly if a diverter is used,
and minimise the number of elbows as the pipe inserts are very restrictive.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will attack the working parts of this unit. All
soldering must be completed and the pipe work thoroughly flushed out in accordance with current Water Supply
Regulations prior to connection of the product.
