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.
You see, every drain in your home is connected to a pipe that moves used water from your house to a sewer in the street; that's right, every toilet, shower, sink, washing machine, dishwasher, and anything else that uses water connects to one singular pipe.
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.
In most cases, shower water and toilet water do go to the same place, which is the sewer or septic system. In a typical plumbing system, all wastewater from the house is collected in a main sewer line and transported to a treatment plant or septic tank.
Gutters and gullies should only collect rainwater and connect to the rainwater drain. Wastewater pipes should not be connected to the rainwater system. If the rainwater gutters and gullies are connected to the wastewater drain, rainwater could overwhelm the drain and cause flooding.
According to Hafren Dyfrdwy Limited (formerly Dee Valley Water Limited), the water in your bathroom taps has usually been stored in a tank in the loft. Hence, unlike the water in your kitchen tap, this water isn't fresh from the mains.
The tap water supply enters the kitchen with an indirect system from the stopcock valve located outside or underneath the sink. The kitchen sink comes directly from the mains, but bathroom water is stored. In a direct system, fresh mains standard water is sent directly to every tap in the home.
1:Can multiple bathroom sinks, baths, showers ect share a common drain pipe ? Yes they can and do all the time.
Whenever you flush the toilet or empty the sink, the wastewater goes down the drain and into a pipe, which takes it to a larger sewer pipe under the road. The sewer then joins our network of other sewers and takes the wastewater to a sewage treatment works.
Your kitchen sink and bathtub have separate drain lines, but they ultimately all connect to a single line that leads into the sewer. If your sink is draining into your bathtub, something has definitely gone wrong somewhere in the plumbing lines.
Tap water travels from a public municipal water treatment system or private well to your faucet. A series of pipes transports the water to your home plumbing. If you receive your water from a public municipal water treatment system, the water usually arrives to your household via main line from the distribution system.
Drain Clogs
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.
Important: Water from kitchen sinks was found to be unsafe for reuse because of the risk of contamination from organic matter such as bacteria from meat. Therefore kitchen greywater must be discharged to a sewer or on-site sewage system.
Can you drink from the bathroom tap? Yes, unless you're in a public space and there's a sign telling you not to do so, bathroom tap water is safe to drink as this comes from the same supply as your kitchen sink.
In pretty much all of the US, the same water runs in your shower, sink, toilet, and kitchen. In a few places, toilets may be plumbed with gray water; that is, water than has been through one of the other systems first. Usually, places that do this make it pretty clear.
While new builds have a direct water system, older homes may be fitted with indirect water systems, according to PlumbNation . While a direct system supplies mains water to every tap in the home, an indirect water system stores water in a tank, usually located in the loft, for use in the bathroom.
Even though homes and hotels are supplied with water safe for drinking, there are too many variables to consider to completely guarantee its safety. So it's best to avoid drinking from a bathroom tap if you can. Stick to bottled water or a kitchen tap."
So, is it safe to drink tap water from the bathroom? Probably not. It's unlikely to kill you but the clean water from the cold tap in your kitchen is a far better option. If you're prone to needing a drink in the night then maybe keep a fresh glass of kitchen tap water on your nightstand.
The main difference in the plumbing of your shower vs your sink is that shower drain pipes have to be 2” in diameter, while sink drain pipes are typically only 1 ½” in diameter.
All the sinks, toilets, and tubs connect to a single drain pipe that leads to the sewer line under your house. This drain line carries all wastewater and sewage away from your home to the city's sewer system. When the sewer line becomes clogged or blocked, wastewater has nowhere to go but back toward your house.
If you're finding yourself ankle-deep in soapy water at the end of your morning shower then it's a sure sign your shower drain has become blocked.
Out-buildings and garages aren't normally connected to the sewerage system. This means most people installing a washing machine are likely to misconnect the waste water pipe to the storm drain instead – which is illegal.
