All of your showers, bathtubs and your washing machine also have P-traps down underneath the drain. The P-trap underneath your sink can easily be removed simply by loosening up the fittings at each end.
P-traps are S-shaped pipe components that keep toxic sewer gases from escaping into your residence. They are required on all plumbing fixtures, including sinks, tubs and showers.
According to regulations, all shower drains are required to have P-traps. This includes all fixtures connected to a building's main plumbing system. P-traps are curved pipes installed under showers and drains of all kinds.
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.
The minimum size trap shall be 1-1/2 inches inside nominal diameter and shall have a water seal of not less than 2 inches and not more than 4 inches. Traps for bath tubs shall be made of cast brass, cast iron, DWV copper, galvanized durham piping, ABS, or PVC.
How far can a trap be from a shower drain? 24″ max. The trap is almost always located directly under the drain and a trap riser cannot exceed 24 inches in height.
The vertical distance from the fixture outlet to the trap weir shall not exceed 24 inches (610 mm), and the horizontal distance shall not exceed 30 inches (610 mm) measured from the centerline of the fixture outlet to the centerline of the inlet of the trap.
One of the most frequent problems with a shower that can result in foul odors emanating from the drain is a clog. Dirt, grime, oils, hair, and other debris can get trapped in the drain line and act as a barrier, preventing similar items from getting washed down the drain.
A blocked p-trap will cause water backflow to occur. The first sign that your p-trap is clogged is when the water in your sink takes longer than average to flow down the sink.
Excess hair, soap residue, and other problems cause a tub to fill faster than it drains during showers or baths. This issue is usually resolved quickly by clearing the clog and getting your pipes flowing freely again.
If your snaking session yields plenty of hair and soap scum, but still leaves you with a slow drain, there's a good chance that the P-trap is still obstructed. To clear it, plug the overflow hole with a rag and fill the tub drain with hot water, which will help to soften and loosen soap scum.
Under normal circumstances, p-traps always contain some water.
One of the features common to most slab-on-grade homes is the bath trap. Bath traps, a type of “slab leave-out”, are located under bathtubs. Why leave a big hole under a bath tub? Generally these openings are left for the convenience of plumbing contractors in case the plumbing needs to be moved or serviced.
by code, a shower must have a 2" trap and drain. this trap must also be properly vented. it can not share a trap with the tub. also, if the 2 drains are together, there is a great chance that when you pull the plug on a tub full of water, some of the water will back up into the shower.
You attach the p-trap directly to the drainage and manuever the p-traps exits into you existing drain. It is not ideal to have the p-trap below the the exit drain because water gravity has to force the water out instead of it flowing downwards naturally.
These traps prevent sewer gases from entering the home and stop heavy items that have fallen down the sink from being completely lost in the plumbing. You must have a p-trap installed under your sink if you want your home to pass inspection in many places, where the building code requires them.
Use a circular saw to cut away the subfloor to gain access to the P-trap. Make your cuts along the floor joists so that you'll have something to support the new subfloor. You may need to use a reciprocating saw to split the piece in two before prying it up.
With most plumbing codes a minimum of 1 1/2" trap is required for a bathtub and 3 1/2' is the maximum distance allowed for a trap arm IF you go exactly at 1/4" per foot drop.
Whether you have a standing shower or bathtub, it will always have a p-trap. The p-trap for showers is located underneath. Like the other fixtures, the shower drain p-trap prevents sewer odors from escaping your pipes.
Bottle traps on wash basins, in showers and behind bath tubs. Discreet design, perfect functionality: Consumers expect this from a waste system designed to make their waste water disappear, never to be seen again. These systems are used when washing hands, bathing, and showering, in the toilet and at the bidet.
A specialized fitting called a p-trap creates a powerful barrier that stops sewer gas and odor from entering your home. The trap is employed in any plumbing system that uses a drain and accepts sanitary waste from tubs, showers and sinks.
The drain is located in the center of the tub.
The position of the tub drain will vary, depending on the size and design of the tub, and you'll need to cut an access hole in the floor at the drain end of the tub to allow for positioning and installing the drain line. This hole should be 9 inches wide and extend at least 12 inches from the wall.
