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.

Misleading
Picture and description suggests order includes multiple valves. Only one delivered.

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.
