W3S166T Hayward 16" Proseries Sand Filter Only

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

As described original equipment, thanks

My hot tub stopped giving a signal to trigger the heating core. I had to replace a whole motherboard and they had the perfect product and with a couple of screws. It went right right in and worked perfectly.

Worked perfectly to get our pool filter motor back up and running.

Great price and it was the exact fit for my TM26 Filter.

Easy to install it took 20-25 minutes and it was back up and running with no issues!

Work perfect
