This lateral 152202 is the correct replacement lateral for the Pentair Triton II TR 30" Fiberglass Sand Filter TR100 140210 built after 1985. The TR100 uses 8 laterals.

Tools Needed


Filter sand appearing in my pool

Written on 4/22/2020 by Guest

After chatting with an INYO pool rep, I was told that I needed laterals which are located at the bottom of my sand filter. I would need make, model, and serial number from the filter to make a proper repair.

I could not find the model number on my sand filter, so I messaged INYO pools support people. I gave them as much info as I could find, make, and tank number. I had a response within 2 days telling me that my model was a TR 100 and they gave me the part number and quantity of laterals I needed to fix the problem.

I ordered what they recommended and they came in promptly so I could make the repair. I opened the top of the tank, vacuumed out all the sand and water and installed the laterals.

Then I filled the filter 1/2 full of water and put in the 600 pounds of sand. Reinstalled the cover and started the pump. Works perfectly!! No sand anymore!!

And I must say that INYO pools support personnel were accurate and correct as to model number and lateral part and quantity. I will definitely be using INYO pools for any future parts and/or assistance I may need in maintaining my swimming pool and spa.

Thank you very much for all your time, consideration, and professionalism you exhibited to me.
