Review on 4 Inch Extend & Lok™ for Effluent Filters by Polylok by Jeremy Tyson

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. Now the sewage tee comes easily over the edge of the riser and I can clean the filter down the road. See my before and after photos. PS I receive no compensation for this post - I'm just a very happy customer :) This saved me thousands of dollars from not having to dig out the tank and reinstall the exhaust pipe.
