HeadSeal.com Replacement Rubber Non-Return Valve - Compatible with All Lay-Z-Spa Models - Ensures Leak-Free Enjoyment and Long-Term Durability for Your Relaxation Haven

So I got this stupidly thinking it would come with instructions or be relatively straightforward to install, and it probably is but I'd suggest that in order to install this you need to deflate the pool so you can push from behind the hole. I thought I'd try installing it whilst it was inflated and it just fell through to the other side and you can't get it back (obviously).My own stupid mistake, but honestly, I'd just recommend paying a few more dollars and getting the disk one which is installed in the screw fitting itself.

Got this to replace the old broken one in a lay a spa Maldives.Got it fitted but now a slow drip has appeared. Maybe not the exact same size as the original. At least the tub is working again.

My lazy spa was loosing water. After stripping down the egg I saw it was coming through the blower tube at the bottom. Ordered this one way valve, fitted it whilst the water was still in the tub using a pair of long noise pilers took a couple of minutes. Topped up the water and left over night and the problem was sorted.Great product.

Used for my lazy spa , it’s just like the one that broke perfect

Good product.
