My basement kitchen sewer/drain pipes completely died. I was faced with the possibility of hacking all of the cement floor (and thus my basement kitchen, bathroom and living space) to find and replace the failing metal pipe.I was going to have to find a place to live AND destroy my home AND fix it up afterward. $30k is obviously conservative.THEN, I found this Trupow pump after learning about some much more expensive Sanif*** products.This Trupow pump fit under my kitchen sink. I ran the waste pipe vertically behind the wall. I took a chance and used .75 inch PVC vertical pipe. Then, for the declining horizontal portion, I used 1 inch pvc. Then, when the pipe exited the house, I coupled the 1 inch pipe to a 1.25 inch pvc. And then I ran that around the side of the house to the cleanout. Everything works beautifully.The Trupow has an automatic switch when it is plugged in. Greywater goes in. The water level reaches a certain point. Trupow turns on. Voila! You have drain water shooting up vertically!SAVED! The trupow works like a champ. Totally reliable. Thanks, Trupow!!
