Yes, a kitchen sink - hence the 'shower' trap As I say, I'm going to bite the bullet and redo the pipework - it's best in the long run! Roger

Thanks mfarrow - I didn't know such things existed! But then I was looking at plastic fittings, and wondered why they don't make one. It seems the running trap brings its own problems, I'll stick to the simpler, if longer way. Incidentally, all this comes about because the plumber who...

Interesting. I'm not sure why not, though I can see there might be a risk of an air lock? IN any event, I've decided, it's best to do the job properly. Lower the pipework and cut a new hole in the wall. There's enough of a drop on the outside to connect to existing pipework outside without...

Hi Squeaky, thanks for post. By 'shower trap' I mean a shallow P-trap ('U' shape). This will keep the outlet above the level of the existing pipework. Soon after the outlet it will enter a running trap, providing the water seal. Once outside, the pipes go into a soil stack. I don't really...

Thanks Nige F, unsurprisingly I'm no expert on the plumbing codes (though I do follow the main rules) I wonder whether the problem with running P traps, with kitchen sinks, is that there is more risk of blockages occurring, given the stuff that goes down them. Presumably the further away from...

Thanks for that PotatoHead - I didn't know of it. I'll look into it However, it still doesn't answer my basic problem; a running trap would do the job just as easily (and cheaper) so why are they prohibited? Cheers Roger

Hi, thanks for reply. Perhaps I misunderstand you, or maybe I didn't explain myself properly. A standard P-trap would leave me with an uphill run in the pipework. A telescopic trap would simply lower the outlet of the trap, making it worse! Roger

The waste outlet on a new sink is lower than the old one, and fitting a standard p-trap would leave it lower than the existing pipework (so no natural run-off). A solution would be a shallow trap (eg shower trap) which would then go into a running trap in the pipework, but I gather running...
