Running Traps

[mfarrow]

Running traps don't bring problems by themselves but poor installation does and two traps in series just means a slow empty.

By the way by sink I assume you mean kitchen sink which will be 40mm / 1.5". A bathroom washbasin is usually the smaller 30mm / 1.25".

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!
