Helps secure round exhaust pipe

Fits snugly in our outlet tube. The PVC was rounded, this was adjusted to perfect roundness making the riser filter easy to install.

Pros
  • Got it!
Cons
  • Not bad, but...

Did the job of installing my new filter - VERY EASY!

The perfect solution for installing my new septic tank filter. It made the hard work very easy, and it was well worth the inflated price.

Pros
  • Satisfied so far
Cons
  • Not sure

Perfect for our septic tank

Perfect for our septic tank. Allows a plumbing tee to be installed in the system if the bulkhead fails. It's easy to install in place and then "weld" the PVC parts in place.

Pros
  • Absolute legend
Cons
  • disappears

Very easy. for heavy duty plumbing

Installation was a breeze with this insert. Doing it with this product alone was worth it. The value of the money saved was a great stress reliever. I'm sure those of you who study this can attest to that. Plumbers are not cheap!

Pros
  • Confident
Cons
  • Could have chosen a newer model

Polylok extension worked great as advertised

Polylok extension worked great as advertised. My tank stopped and pulled the triple waste filter out from under the rim of the riser. (see photos) There was no way to clean it and it was clogged causing my tank to overflow. The solution came with the Polylok extension. Once the tank was evacuated, I was able to cut the old sewer tee right up against the wall of the outlet pipe and then hit the extension with a rubber mallet, getting just enough pipe sticking out to reattach the new sewer tee…

Pros
  • Delivery was very quick
Cons
  • Questionable purchase for seniors
