Topside Part, Button Diaphragm - 2000/4000

This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!

Excellent service!

PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping

My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.

Good quality just ordered wrong size and also need thicker cover

Fit perfectly, and fast shipping

I accidentally broke the original **** by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!

Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.

Haven't received yet but I'm sure it'll be great

Ordered on Saturday and we're delivered by Tuesday! Great products and great prices!

PST pool supplies are great to work with. I was having trouble finding this heat exchanger . Everywhere I looked, it was out of stock or back ordered. I contacted the manufacturer about buying the heat exchanger. They told me I couldn't buy it because I wasn't a dealer. If I was a dealer, they would be able to take the order. And make one, it would take 5 to 8 weeks. I contacted PST they put my order in and I received it in about six weeks. Fantastic people to work with. Thanks Tim
