The 4 hole bushings are horrible quality as on a repair job, it is hard to get the drain pipes perfectly fitted into the bushings , thus they leak. A better system would have been 4 couplings molded into the box and drainage pipes join to the coupling. Even with loads of putty, still will drip, drip. Box could be a little bigger in dimension also.
Solid construction, heavy duty materials, totally satisfied!
Great product. Sturdy construction.
The box seems to work well. The plastic seals on the other hand are pretty lightweight and cheap. No directions on which way seals should go in, so I had to zoom in on pictures on website. The plug leaks slowly- just drips. All pipes have to go through seals perfectly straight and level, otherwise they leak. Even when installed square and level, they still slowly leak. I was sure to use the correct seals for the pipe I’m using, although again no directions- had to look it up on website. I‘m sure they will leak even more after years of the soil settling. Also, due to the slow leak, I’m betting roots will find the water and get their way in. I recommend using silicone caulk on both sides of the seal and on plug, then it should work well. It’s gonna be a pain to try to add silicone after it’s installed and water is in box...
