And just when I thought I was getting my plumbing well organised, I bumped into the terms 'check valve' and 'double check valve' in a YooChube video about fitting taps.
Scheiße - schon wieder , verdammt noch mal !
At this stage of the game, I'm getting really tired: folks, could someone give me a quick sentence on where they should be fitted - and maybe a quick word or two of sageness about how not to use them? Please?
Danke.
