The container inlet for a toilet contains three different types of pipes. What plumbing is needed for toilet? 6 Step The water supply, which usually consists of 1/2 inch copper tubing, ends at the shutoff valve at the bottom of the tank. The waste line, which can be 3 or 4 inch PVC pipe, connects to the sewer via a vertical waste pile and connects to the toilet via a toilet bowl flange.
Also, the waste line should be vented with a 2-inch pipe that ends outside. The configuration of these pipes depends on the location of the toilet relative to the pre-existing plumbing and the structure of the house. As plumber near me service, we work 24 hours a day.
Waste and Ventilation Pipes
Install a 4-inch vertical PVC pipe running from a point at least one foot above the toilet bowl to the drain. This is a pile of earth and must be connected to the sewer with a long sweep Y-joint or “Y” shaped fitting. If the sewer pipe is plastic, use a plastic star, but if the sewer is cast iron, insert a cast iron cable with a threaded entry and screw on a PVC adapter. Adhere the dirt pile to the plastic Y or adapter with PVC cement.
Place the toilet drain in the bathroom where it will provide enough space for the toilet when installed; Suitable for most toilets 12 inches from the back wall.
With a reciprocating saw, dig a 3- or 4-inch diameter hole in the subfloor for drainage. The size of the hole depends on the size of the waste pipe you plan to use. A 3-inch line provides better drainage, but a 4-inch pipe is required if the distance to the soil pile is more than 6 feet.
Insert a toilet bowl flange of the appropriate diameter into the hole in the bathroom and screw it into the subfloor with a screwdriver. The flange holds the toilet to the floor and creates the connection between the toilet and the waste line. Glue a cabinet bracket to the flange pipe under the subfloor with PVC cement. The elbow should be pointed in the direction of the pile of soil.
Attach the PVC pipe to the elbow and extend it into the soil pile maintaining a downward slope of 1/8 to 1/4 inch per foot to the pile. Cut the stack and glue it to a 4-inch piece of sanitary tee with a 3- or 4-inch opening, depending on the size of the waste line. Glue the waste line to the tee.
Reduce the size of the opening at the top of the soil stack to 2 inches with a reducing coupling. Adhere the 2-inch PVC pipe to the reducer and stretch it across the roof. This pipe vents the toilet and should terminate 1 foot above the roofline.
Water Supply Pipes
Choose an existing copper pipe that carries cold water near the toilet and turn off the water to that pipe. Cut it with a pipe cutter and solder a copper tee with a 1/2-inch outlet.
Install a supply line for the toilet with 1/2-inch copper pipe and fittings. It should extend from the tee to the wall behind the toilet and extend about 2 inches beyond the wall under the tank. After installing the supply line, solder all the joints and attach the line to a post in the wall behind the toilet with a pipe clamp.
Terminate the water supply line with a shut-off valve. You can solder the valve to the pipes or install a valve with compression fittings. Make sure the valve is closed before turning the water back on.
