Don’t talk to me about strange plumbing… :d When I moved in to my 70′s flat, I found that when the washing-machine emptied, the water came up into the bath! So I plugged the bath – the water came up the bath overflow instead. Which was how I found out that the overflow leaked.
In the course of fixing this, I discovered that the bath s-bend ‘hung too low’ when it was installed, so the crafty builders had dug a hole into the concrete floor under the bath to fit it in! In a first-floor flat. So when the overflow leaked, it wasn’t much, but the water went straight down the hole and invaded my downstairs neighbour’s bathroom ceiling. So I had to pay to fix that, too. Honestly, you couldn’t make it up…
Anyway, all semi-fixed now. But I’d never risk a dishwasher, even if I had room for one! Things just barely hang together as it is.

Please enter me in the draw – I’d love to try the frags you spoke about, even if they are men’s.

How is the puppy? Did you ever get to try the CdG White?

Have a good day!

P.S. I mean this in an entirely unpunny way: I do hope you get your plumbing fixed with minimal $ and trouble.
