Plumbing and Drain Tips for Bathroom Installation

Video Transcript

"We are going to talk a little bit about the toilet flange here and this is where your toilet will sit. This is a 3 inch toilet flange and it ties down into our main 3 inch AVS sewer line and again we have that 1/8 inch fall per foot so that the solids from the toilet will flow smoothly and evenly out into the main sewer line. Then here we have another pea trap which is installed for the shower so that when the shower pan is installed in the corner in the very center the drain will be attached and this is where all the water from the shower will drain in and again the pea trap acts as the blocker for the shower. This is the pea trap for the shower and again you can see where I have some insulation stuffed in the opening from the debris did not fall in there and clog up my pea trap. I will remove that as we proceed on and start to hook things up. You can see the main sewer line down there, the 3 inch ABS line. I had to take my demolition hammer and chisel a hole through the foundation. This particular house has a 36 inch deep and 6 inch wide foundation which is solid cement and I had to chisel my way through the hole in order to run my sewer pipe outside and tie into the main sewer line. We also had to put a larger ABS sleeve, a 4 inch coupling and that helps to protect that ABS pipe from any damage that might occur from rubbing against the concrete. What we are looking at now is the original drain for the washing machine. When the house was built, you can see they used 2 inch ABS, it is a 2 x 1 and 1/s inch sanitary tee and at that time the code was that for the drain you had to have 2 inch ABS and for the vent which you can see coming out of the top of that tee was 1 and 1/2 inch. The code has changed since then and the smallest you can use is 2 inch for your vent line. What we have done instead of removing all of this, we have cut off where the old pea trap tied into this drain and we have just put a cap on it and it will remain in the wall and we will just cover it up with the dry wall and no one will ever know it was there."
