Hi I have a rangemaster kitchen tap, with a curved spout and quarter turn valves.

It's about 2 years old.

With both valves off there is no leak.

When one valve only is on, water leaks from the top of the opposite valve stem. It's like the water has traveled to the opposite side, above the cartridge, and then leaks out.

Any ideas? Should there be a non-return valve in the middle somewhere (under where the spout swivels around??)

Just to add a few more details it's a
