Thanks to a bit of bodgery with garden hose and jubilee clips the new shower pump works. Too soon to say whether it will be much of an improvement in the wet but on paper the delivery rate is a lot better.

But the non-return valve is still pants and I am going to have to figure out how to get an inline one into the circuit.

Other job before Friday is to check the generator just in case.

Between Friday and Knockers I can rip the shower plumbing apart to put the shower on the other side and install new shower rail and curtains. Big Dick promises me that my awning will be fixed by then too.

So, John, in case it is any use I have a spare water pump.
