Cistern was constantly filling and going into pan, this inlet valve was the culprit, surprisingly easy to fit and problem gone

Handy find
I definitely didn’t expect to find this plumbing item on Amazon after three plumbing merchants didn’t stock the part. A definite money saver, fitted in minuets. Saved a load of cash buying and fitting myself.

Not 10 items
This is very misleading and makes you think you are ordering 10. ordering one is very expensive and I would suggest you look elsewhere.

Hard to find and expensive, but worth it. Fit and finish great as expected. Original lasted 20 years.
