On board water tanks are too large to fill for just a day
We use a 10 litre plastic jerrycan that fits in the seat base next to
the water pump. The plastic feed pipe from the inboard tank has been cut
and using 15mm plastic push-fit plumbing fittings (from Homebase or similar) a
tee-piece and two isolator valves, the water can be supplied from
either container. A Whale in line non-return valve to the end of
the dip tube in the jerrycan prevents the pipe emptying or siphoning back
when removing the container.
Using two 10 litre containers we have found
this arrangement to be sufficient for an overnight stay and easier for
topping up than trying to get near a standpipe with a hose.
I have also
fitted isolator valves in the upstream and downstream pipes to the Carver
Cascade water heater to stop it filling when the pump is operating and it
has been drained for the Winter. Note
that two valves are better in this arrangement to prevent possible
back flow from the mixer taps although there is a check-valve in the
Cascade unit. The flexible hot and cold water hoses can be fitted
over short lengths of 15mm rigid plastic and copper plumbing tubing with
jubilee clips for security on the pressurised side on the pump circuit. On
the inlet side, if using rigid 15mm upvc tubing remember to fit the
stainless steel sleeve inserts if using standard brass isolator valves
with compression fittings.
