Do they also work to do the opposite: to keep air out? I have had
times when I have drained the pipes whilst working on them but the
shower instructions say the shower pump should not be used to prime
the shower and that it can be damaged by pumping air.
Valves under the bath seem the easiest place but if you silicone the
panel in place to keep the water out (essential if it's an mdf panel),
it's not always quick and easy to get to the valves. I'm not sure
where else you could put them if your pipes are not visible though.
