Safety Concerns Over a Shower Upgrade??

[DefyG]

Installed a 11kW unit earlier this year and manufacturers instructions said 16mm!!! (It didn't read as a recommendation either).

Just want to says thanks again for all the advice and to give a follow up...

I popped around there today and I think I got the message across. When I ventured that he will in effect be wasting £400 as the new shower simply won't work, I think that concentrated his mind.

I also suggested he get in a proper plumber to look at the low water pressure issue first, as he might be better considering a small power shower...

Anyway time will tell, as you can only do so much to help....

Thanks again,
Peter
