Rated 5 out of 5 by from Easy fit Decided to replace this as I had to replace the close coupling seal. Good product and easy to instal. You do need a large spanner to ensure the seal is tight against the cistern and close coupling mount. Dual flush works well and like the built in overflow. Also like that the fact that it will be serviceable in future without having to pull whole cistern off.

Rated 1 out of 5 by from Disappointed If there is a built in overflow, this one got missed in production. Load of rubbish.

Rated 5 out of 5 by from Easy to fit As an RF engineer tasked to fix the work loo I envisioned hours of sealing and messing around. This was a replacement for the one fitted and it took less than 5 minutes from opening the box to working loo. Easier than fixing a radar system except now I have a reputation

Size of out let

Hi I need a handle flushed 2 inch outlet do you sell anything like this?
Asked by: RichardC83

What height to adjust it to?

This siphon can be adjusted between 7½ and 9½, but doesn't give any details on which to choose or why. Currently I have it high enough that it fits inside the cistern without too much spare, just because the old one looked like that.
Asked by: RichardTea

Wrong one, what do I need

Ive purchased this Thomas Dudley 237. After getting all set up, I found it was leaking and that it is too wide and was hard up against the cistern causing the siphon not to sit squarely on its base. I need one thats 2cm narrower . Help please.
Asked by: PenGosModel

Will this work with a right hand side flush?

It worked OK for me with a right hand flush.

Does the internal overflow adjust with the height adjustment?

If you adjust the siphon height to 7.5 inches is the overflow set at 7.5 inches?
