It should go without saying that your basement floor drain is one of the most important parts of your homes plumbing. Without it, there would be no place for water to exit, leaving your lowest level in disarray. Knowing how your basement floor drain works, and why it is important, is essential for when an emergency strikes.

At the lowest point on your basement floor, the floor drain acts as the outlet for any unwanted water, whether its from a heavy rain, condensation from your HVAC unit, or a leaking water heater. The drain can connect to one of three things, either to the sewer system or to a sump pit. Drains connected to the sewer systemare suitable for draining a washing machine, water softener or a basement laundry sink. If you connect the drain to a sump pit, it may be against your local ordinance to drain any water with detergents, salt or chemicals.

The third connection is if your basement floor is lower than where the main sewer line leaves your home. Here, your drain will connect to a sewer pit with an ejector pump. This is not the same as a sump pit, so draining a washing machine or sink is suitable in this situation.

Newer drains come from PVC piping, particularly the catch bowl and drainpipe. They may construct older drains from cast iron, and in less common instances, they can make older drains from clay tile.

Strong Sewage Smell Coming From Your Plumbing Fixtures

This is probably one of the easiest ways to determine if you have a clog in your sewage system. If you start to get the hint of a sewage smell from any of your plumbing fixtures, then it means that theres probably a clog in your sewer line.

If you experience any of these, it means that its probably time to get your sewer line fixed. If you know fundamental fixes for your sewer line, you can try to fix it yourself. Otherwise, it may be the time to call for professional plumbers from your area.

Washing Machine And Washtub Basin Backing Up

If your washing machine caused the problem and it resulted in a lot of water, no need to panic. This is one of the easier issues to fix. You’ll need to turn the machine off and look for the strainer on the drain hose. Most usually it is the strainer that became blocked somehow.

The same thing can happen on a washtub where a strainer, or, if you don’t have one, a p-trap becomes clogged or filled with debris. You can clean it by hand, with baking soda-vinegar solution, or a plumbing snake.

The important thing to note is that if either of these is located in the basement, then it is more serious of an issue. It means that the washing machine or washtub are perfectly fine, whereas the blockage is further down in the drain system. This requires help from a professional.

There are many more things that can cause the basement sewer line to back up. But one thing remains the same always consult a professional. An experienced plumber will have adequate tools and knowledge to fix the issue in no time.

Backup Of Storm Sewer Water From The Municipal Storm Sewer System

In many older houses with basements , there is a perimeter foundation drain outside the exterior wall, at the level of the basement floor, next to the footings. A pipe was usually installed from the perimeter foundation drain to the street where it was connected to the city storm sewer system.

This can become a problem as the city storm sewer system becomes too small when more development causes more rain runoff. When this happens, the rainwater in the sewer system can get so high that water flows backwards toward the house.

Usually, the installation of an interior perimeter basement drain system connected to a sump pump will take care of the problem. If it doesn’t, the alternative is to dig up and cap the pipe that is running from the house to the street from the perimeter foundation drain. However, this is not always possible many times, this pipe is also draining sanitary waste from toilets and sinks in the house.

If you believe you have this problem, contact an experienced contractor for advice.

If Water Backs Up Out Of Your Floor Drain Its Not A Floor Drain Problem

No joke. When water backs up out of a floor drain, it usually means there is a clog in the drain line, not the floor drain itself. When there is a clog in the main building drain and water is run down a drain from an upper fixture, water will back up in the drain line until it finds somewhere else to come out. Thatll be the lowest fixture. In most homes, the lowest fixture is the floor drain.

If a home doesnt have a floor drain, water will still back up out of the lowest fixture. That might be a basement shower, bathtub, standpipe, or a sink. Ive seen all of these happen, and you can too by clicking on the video compilation below.

In all of these cases, there was no problem with the fixture that was backing up. The problem exists with a drain line downstream from the fixture. The best way to clear a clogged drain is to have the drain line cleaned out professionally. If you choose to try it yourself, be warned: this is very dirty work. Once you find the clog, whatever you pull out of your drain is going to be gross. Really gross. Thats part of the reason that most people hire out this work.

For many homeowners with old homes, its standard practice to have a drain cleaning service come out to auger the drain lines every year. This helps to clear trees roots out of the drain line and is done as preventative maintenance.
