What if new kitchen sink drain doesn’t line up with existing pipes?

In general, if the P-trap doesn’t line up with the drain, you can adjust the length and height of your drainpipes by cutting them or simply slipping them in and out of their fittings.

Does every drain need a vent?





Without getting too far into building science, a general plumbing rule of thumb is that every drain needs a trap, and every trap needs a vent. All those traps and drains are designed to prevent sewer gas from entering your home.

Can p-trap be lower than drain pipe?

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. They both work and have seen it many times.

Can a shower and sink share a drain?

Is It Possible to Have the Same Drain for the Shower and Sink? Yes, the drain for the shower and the sink can be the same. The shower and sink can use the same drain pipe if it is well below the sink and shower level.

Will a sink drain without a vent?

Without venting, the negative pressure caused by the flow of draining water can potentially suck water out of the drain trap and allow sewer gases to enter the home. The vents allow air into the drain pipes to help keep the drain flowing properly.

What happens if plumbing is not vented?





Poorly-vented drain lines will not be able to effectively move wastewater and solid waste out of your building. This could lead to problems such as overflowing drains, backed-up toilets, and similar plumbing issues.

Are toilet drains and sink drains connected?

Plumbing contractors can connect drain lines in the floor beneath the bathroom and install a vent that will allow water and waste to drain without forming an airlock. The sink drain will empty into the toilet drain line because the toilet has the largest drainpipe.

Do toilets and sinks use the same drain?

The toilet has the largest drainpipe, so the sink drain, which is smaller in diameter, will empty into the toilet drain line.

Why does my bathtub fill with water when I shower?

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.

Why is poop coming out of my tub?



The most common reason for sewage coming up through your bathtub is a clogged sewer line. 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 I flush the toilet it comes up in the shower?

If you see used water from the toilet backing up into shower or tub drains though, that’s a sign of a clogged sewer main. Since something is blocking the wastewater, it has no other choice but to back up. Since your toilet is set higher, the water is more likely to rise out of the lower tub or shower drain.

Are all drains in a house connected?

Your sinks, toilets, showers, and washing machine each have their own branch line drains. These branch lines connect to your main house drain at some point. If your main house drain becomes clogged, all of the other drains in the house can back up.

Do drains go under houses?



They are usually behind the houses by a few metres. Sometimes people build extensions over them (this is not actually allowed). In terraces they usually run behind all the houses, parallel with the road, then come forwards to join the sewer under the road at the end of the terrace.

How do you find out where my drains are?

Perhaps the best way to obtain this information is to contact your local water authority, which is also the organization that would be responsible for any problems that may arise with shared drains. Another way to check and see if you have a shared drain is to check with the sewage company that services your area.

Where do drains lead to?

If you are not connected to a sewer system, your water drains into a septic tank. In the tank most of the solids settle out while the liquid water will go on to flow through underground pipes that have holes drilled into them; those holes allow the water to seep out and into the ground.

Do drains lead to ocean?

Marine outfalls are pipes that discharge wastewater directly into the ocean, after only basic or no treatment. The idea is that the ocean is large enough that the dispersing will make the impact negligible.

What happens to water after it goes down the drain?



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.
