Triton t300si stabiliser valve main seal - need to replace?

[XmisterIS]

The other day our Triton t300si shower began leaking like a good'un. I have just taken the back off and the leak is coming from the top of the stabiliser valve unit, where the main seal sits - water spurts out from between the body of the unit and the plastic end cap.

See the images below for a better understanding:

1) The stabiliser is item 10 in this image:

2) The stabiliser itself looks like this:

The water is spraying out from the top, where the end cap under the four screws meets the body of the unit.

So, I have removed the stabiliser, undone the four screws, and inside is the main valve seal, which looks like this:

All well and good, you might think, but the valve seal from our shower looks perfectly ok - not torn/perished/damaged as you might expect.

I can order a new valve seal, but I fear it may not correct the problem.

Any ideas? Or can a valve seal be knackered although it doesn't look like there is anything wrong with it?[/img]

Inspect both valve seal and the casing it sit in. It may be a pin hole on the seal that you never notice it. Check around groove the seal sit, both on main body and the top end cap.

Could be a split in plastic body. Had this a few times.
