How does bathtub plumbing work

The toilet uses only cold, untreated water. The drains for all three fixtures connect to one larger drain pipe underneath the floor, which sends the wastewater down to the main sewer line.

This drain pipe is also attached to a vent stack, a vertical pipe that runs up inside the wall to the roof. The vent stack allows the necessary suction for the wastewater to flow downward. As mentioned, the bathtub has two main features: the water supply and the drain, and it's good to understand its plumbing in a little more detail. There are two water supply lines to the bathtub: one for cold water, straight from the main water supply, and one for hot water, which comes from the water heater.

Each has its own shutoff valve in case of an emergency. The two supply lines meet at the faucet, where the handle or handles to control the temperature of the water. 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. The entire process takes less than a minute and is made possible by basic physics.

This problem is usually solved using different chemicals. After a while on some bathtubs cracks can appear which causes the leaking. Therefore, you need to inspect each part of the bathtub in detail to find where the crack is located, and thus stopped the water from leaking. Bathtubs can come in combination with two drains. The bathtub drain is located at the bottom of the tub, at the drain hole, in the middle, or at one end.

The main role of the Bathtub drain is to let water out of the tub. Screwed to the siphon, it provides the link between the latter and the bathtub. It can be closed, allowing the tub to be used as a shower or a bath.

Most often, the plug is closed by a shutter embedded in the overflow and connected to the plug by a cable. But it is quite possible to prefer a simple stopper or a pop-up system to be operated with the foot. Drain and shutter participate in the aesthetics of the bathtub. Two different assemblies of the drain are most commonly used: plunger-type and pop-up. The plunger works on the principle that you just insert it into the hole and seal the drain opening.

The pop-up drain works on the push principle. With the press of your feet, it goes up or down. When the drain stopper is up, the water can flows into it. In the bathtub, the overflow serves as protection to stop water when it reaches a certain level and it is located a few centimeters from the edge of the tub.

The anti-overflow device is in most cases a hole that, more or less is hidden and that is connected by a flexible pipe to the upper part of the drain. As necessary as the overflow is, some freestanding bathtubs are not equipped with it. Keep in mind that an anti-overflow safety device is most often set at the level of the emptying plug: so that the plug does not close and the water can be evacuated; or it incorporates the overflow system, which then operates with the weight of the water bathtub.

There are different types of bathtubs: the built-in bathtub, free-standing bathtubs, whirlpool tubs, and shower baths. When it comes to shapes; All bathtub shapes are suitable for recessed installation: rectangular, square, round, oval, asymmetrical, etc.

The dimensions of the built-in bathtub depend on the chosen shape. Choose your bathtub according to the size of your bathroom. Most common bathtub types:. It is the traditional material of the bathtub par excellence. This means that it continuously drains water that reaches its level. The overflow drain can work effectively if the pipes are not clogged and if the water level stays several inches beneath the rim of the bathtub.

Ultimately, this keeps water from pouring onto the floor. There are two primary types of overflow drains that you can use. 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.
