Bathtub plumbing

Most bathrooms require 5 water lines: a hot and cold line for both the bathtub/shower and the sink, and a cold water line for the toilet. Each fixture and house are different, so hire a pipefitter or plumber to run the lines for you if possible.

How does a bathtub plumbing work?

Turning the handles open valves that allow water to pass through. The water then issues from the bathtub spout or is sent up through a single vertical pipe to the showerhead. After use, the dirty wastewater goes down the tub drain, through a P trap, and to the larger drain pipe under the floor.

Does a bathtub need a P trap?

Does a bathtub need a P-Trap? Yes, you should always install a P-Trap as part of the plumbing of a bathtub or any other wastewater drain system. Failure to include a P-Trap could result in foul smells, harmful gases, and small animals entering through your tub's drain.

How is a bathtub drain connected?

A tub drain consists of two separate parts. The drain basket which connects to the drain shoe, and the drain overflow which connects to the drain shoe pipe. When these two parts connect together, they flow into the drain waste pipe which connects to the sewer or septic drain pipe.

Why do baths come with no tap holes?

A pipe shroud is used to cover the pipework for the taps on freestanding baths with tap holes. Stand pipes are designed for baths without tap holes – raising the taps so they rise over the sides and into the tub.

What do you put under a bathtub for support?

The mortar conforms to the contours of the tub, and when it sets, it prevents the tub from moving and supports the weight. Both regular thinset mortar and floor leveling compound are suitable. A series of strategically placed piles is easier to control than a full bed, and it provides comparable support for the tub.

Why do bathtubs have two drains?

Types of Overflow Drains The first is a traditional overflow, and the second is an integral overflow. With a conventional overflow, a hole is cut into the side of the bathtub. This allows water that has collected inside and on the outer walls to drain. The second is an integral overflow.

Where does the water from my bathtub go?

When your plumbing systems are in working order, your bathtub drains tub and shower water down your pipes and into your sewer. Your bathtub and toilet drain down separate pipes until they reach the main sewer line, which is the primary pipe to which all drains in your house lead.

Where does the water go in a bathtub overflow?

The water that enters the overflow hole, goes down a pipe which is connected to the tub floor drain. With a well-functioning overflow drain, excess water will flow out the overflow hole, through the pipe and into the drain so as not to cause any damage to your bathroom or anything under or around the tub.

Can a shower and toilet share the same drain?

In short, it is possible to connect the toilet drainage line and the shower drainage line, as long as they both have separate waste trap arms. However, do note that combining them may also lead to blockages, which can cause smells to come from certain drains.

What's the difference between an S-trap and P-trap?

With an S-trap, the drainpipe drops down from the sink and into a conventional trap. It then loops over and exits downward. In a P-trap configuration, the drain also comes down from the sink and into the trap, but instead of looping over and back down, the drain enters a horizontal run before exiting downward.

What is an S-trap vs P-trap?

The difference between the two traps is simple: the shape. An S-trap flows down from the drain, curves up, then curves back down. The P-trap also flows down from the drain and curves, but the curve finishes on a horizontal pipe that takes the waste out.

Does a tub have to be perfectly level?
