The general answer is that the showers and toilets can use the same drain, but they should not be sharing the same waste trap arm. There are other factors to consider as well, such as whether your drains lead to the main sewer line, or if there are septic tanks that are used in your city or town.
If you are remodeling your bathroom and find that the shower will be installed over the location of the previous toilet, you can simply change the toilet drain to a shower drain.
Sewage – all the waste water that goes down our sinks, out of the shower, from our washing machines and even from our toilets. Sewer vent – like a chimney for the sewerage system.
When the shower and toilet are both clogged, the obstruction will likely be downstream from the area where the shower and toilet connect with the underlying sewer main. Such simultaneously clogging is a sign the obstruction is so deep that it backs up both drains.
Is the same pipe used for drainage from a sink, a shower, and a toilet? Yes. Most homes in USA connect all the drains from all the plumbing fixtures to a single sewer pipe that flows out to a common neighborhood sewer under the street. If you pee in the sink or shower it goes to the same sewer as peeing in your toilet.
Wastewater must not flow into the surface water drain. Unless your house is on a combined drains system, it needs separate drain connections to collect wastewater and rainwater. Homeowners and landlords are responsible for checking they have separate drain connections from their home.
Connect the sink drainpipe to the toilet drainpipe using a 2-inch-to-3-inch sweeping-Y connector. The sink drain should enter the toilet drain from above, and the 2-inch opening for the sink drain should extend upward from the 3-inch horizontal drainpipe to prevent backflow issues.
Air coming in – When your sewer venting system becomes blocked, it creates severe pressure differences in your system where air cannot come in. This causes air to be sucked into your system via your drains, shower, and tub. This is where the gurgling noise comes from.
When the toilet is flushed, the rush of water into the sewer is pulling air through the tub drain causing the gurgling noise. First, make sure the plumbing vents extend above the roof. In cold weather, simply run hot water to the sinks and look outside to see if steam is coming out of the roof vent pipes.
Showers and toilets have one thing in common: plumbing. And while you can't always interchange things in a home when working on a remodel project, you can convert your shower into an area for a toilet simply by doing some demolition and remodel work, along with replacing the plumbing.
To do this, pour a cup of freshly boiled hot water down the drain. Next, pour a cup of baking soda into the drain. Follow this with a cup of half boiling water and half cleaning vinegar, and put the plug into the drain. Leave it in for five to ten minutes to allow the solution to work its magic.
Where does the water go after you flush the toilet or drain the sinks in your home? When the wastewater flushed from your toilet or drained from your household sinks, washing machine, or dishwasher leaves your home, it flows through your community's sanitary sewer system to a wastewater treatment facility.
Don't do it! toilet waste pipe is significantly larger than a standard washing machine waste for a very good reason!
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.
There are several common causes for a sewage odor coming up from the shower drain, including a clog in the drain line, a dry or dirty P-trap, mold or biofilm build-up, and leaking drain lines in the walls, ceiling, or under the floor.
One of the most common causes of a toilet that is bubbling or gurgling is a blocked drain. If your toilet's drain is blocked, it can cause water to back up in the pipes, leading to bubbling or gurgling noises.
Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
If water is not draining fast enough in the shower, you likely have a clogged drain. If you are standing in a puddle of water at the end of your shower, your drain is likely clogged. A clogged shower drain often smells terrible as well.
A gurgling or bubbling toilet is a symptom of a more serious issue such as a blocked sewer pipe. If this is the case, you may also notice other concerns such as a slow draining toilet, shower or sink, or a bad odour coming from the drain. This will depend where in the line the blockage is.
What Causes Gurgling? Gurgling is caused when something is preventing water or air from flowing through your drains. As the water slowly travels through your drains, air bubbles begin to form and create a gurgling sound. Whether it's your sink, toilet or shower, even floor drains all can make that gurgling sound.
They aren't just practical either, they're efficient too. Water used to wash your hands also tops up the cistern so you can reduce the water you use, even if it's just by a little.
Two sinks can share a trap as long as the centerline of the outlet (tailpiece) of both sinks is not more than 30-inches horizontally from the trap centerline, per International Plumbing Code (IRC P3201. 6), as shown in the diagram above.
All the sinks, toilets, and tubs connect to a single drain pipe that leads to the sewer line under your house.
