Fernco QT-400 4-in. Qwik Tee

I Y'd new sewer line from pool house to existing house drain. Had to add and glue about 1 1/2" of bushing over ends of existing pipe for a good fit. Need to completely move loosened clamps to allow for twisting fits into place. Good fitment and the clamps are sturdy. I recommend using a socket on the clamps rather than a screwdriver. This fitting is 90 degree with each opening the same size. My project required a 45 along with a 22 1/2 that went right into this tee with no bushing. Personally I like a Dremel with a cutoff wheel to cut right through the sewer pipe with only a little to deburr and no big cracked pieces to deal with.

Plumber reluctant to use (rubber) on old ceramic sewer pipe with tree-root problems. Hint: Don't debate with your doctor/dentist/or plumber ! We have several flexible fittings inside the house, all perfect. However, the 73yr old clay/cement sewer line (60 feet to the alley), will not survive modern root-removal machines.

Product had the perfect amount of flexibility and rigidity. The clamps were the proper size and appeared to be of good quality.

Exactly what I needed. Good quality and price!

I liked everything about this product! Mold casting looked perfect. Weight , durability, thickness and very rigid with enough give to just make it over stationary pipes. I used a little silicone lube for assistance. If in the future this section needs to be snaked I feel there will be no chance of a puncture.

Worth to leave a comment. Perfectly fitted the job to insert a drain connection in the main drain. The main drain was in cast iron, cut and put this with no problems and super fast.

Great for a tap into my underground gutter drainage PVC pipe. But was too loose, so I made “sleeves” from the female joints of a sacrificial connector and glued them to the old pipe for a snug fit.

Worked great for tying in cast iron and pvc pipe
