Lazy Spa Compatible Clip On Non-Return Valve for the A Connection, easily installed, fits Air Jet and Hydro Jet models.

This absolutely saved the day on the tub. The inner valve disintegrated leading to this purchase. Very simple to fit, even with the hot tub remaining full, it slipped in to place and stopped the leak/back flow immediately. Still allowing the air through, this has given us more years ahead to use the tub. Marvellous.

No more water gushing out of inlet A and subsequent leaking from the pump unit when connected. Lay-Z-Spa suggested I needed a new pump unit but ordered this instead and fitted it easily in 2 mins. No more leaking and I have bubbles back in the hot tub (Milan)

Not cheap for what it is but it does work and prevents water leak back from the air tube on LazySpa hot tubs.

Doesn't work sadly, was really hoping it would as it's much easier to fit than the others but nope just leaked straight away 😔

Hawaii tub air inlet coupling was leaking quite substantially back into pump. This device fits snugly in the pipe and created a perfect new seal. Can now run the air and bubbles again.

Amazing product easy to fit and works well 👍

Great item works well saved me buying a new hot tub

When i first fitted this non return valve i got no bubbles so like many others i thought it didn't fix the fault. On further investigation and after emptying the hot tub I found that the old non return valve which is located down the end of the pipe was stuck and not allowing air into the tub. i cleared this old valve out the way and now i have a hot tub just like new. No more water in my pump and lots of bubbles.
