U9-226Z Pentair Buna 70 O-Ring #2-226 1.5" Diffuser

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

Fast service

After much research the value of the product is good. It was shipped fairly quick and it arrive in a well-protected package.

Very happy with this purchase fits and work as described fast shipping

Loved how fast it got here. It has small wiring and I was glad it was in a protective envelope and it arrived without breaking.
