Let customers speak for us
Exact replacement Weir door that fit perfectly! Solved the problem of my old worn out doors!
Excellent price on well built wet end. Shipping was fairly fast as well
I installed the new wire with no problem fit right in and clamp her down like they took the old one out works great now
PST Pool Supply Company is a wonderful company to do business with. The customer always comes first with them.
Thanks
This worked great for our Bullfrog X6L. Plug and play actually worked as it should and connected right up. Shipping took a bit long, but given it was free, I'm not complaining. Also it was 75% cheaper than buying from the bullfrog dealer.
Very good customer service. The post office screwed up my order and they responded to my msg very quickly and reshipped another part free of charge. 👍👍
I was looking for a part for an old pool filter housing.
Fortunately, I found PST. They had the part and I ordered it on a Friday, and it arrived on Tuesday by FedEx.
The filter housing was updated and different, but once I installed it, it fit perfectly and worked just as it should. I am so pleased with not only the part that I received but also the expert service and at a fair and excellent price.
Thank you, PST Pool Supply, for coming to my rescue. I highly recommend you checking with PST for your pool needs!
Replacement part was correct and vacuum is back together and being used.
Easy fix for small leak around valve in concrete pool.
Definitely recommend this shop!
We are running big and deep pool and we get all what we need from here
I had trouble finding the right part that would fit. PST helped me figure out exactly the right part and fit.
Helped me get my light installed correctly after liner change
This machine cleans 10 times better than my previous one and is worth the cost. However, I’ve only had it for 2 weeks. The last one lasted about 6 months and never cleaned well even though it had 4 stars when I bought it. I hope this new one remains strong for a few years
