No, but I bet they will be.
I notice Steve or whoever it is who now owns exceed have a univalve plus. £45-£65
Seems that after making a reliable product the parts or mechs were down graded so we had to replace or service them.
Now it seems they are sticking in better orings and yes a better spring.
Some one needs to invent something to challenge this product

Our original 2 Univalves are still working fine. I purchased them from Cleaning Warehouse in February 2016, and they were £78.58 for the 2.
They get opened occasionally and lubricated with a thin smear of silicon grease. I've only had one fail to shut-off. It was the tiny O Ring on the plunger that had come off. I glued it back in place and it is still working today.
Steve has a patent on the pull on pull off design so no one can copy it. Remember the Aquatap that Peter Fogwill designed and then Alex tried to refine it. It never took off or was that reliable.
The basic price of the Univalve hasn't gone up that much tbh.
Unfortunately since then, Steve has gone VAT registered which has pushed the selling price up to none VAT registered users. I purchased 2 x Aquadaptors on the 7 August 2013 for a total of £89.36.
