A Short Guide to Venting Washing Machine Drainpipes

Must Read

The washing machine is one of the most-used pieces of equipment in the home, which is why any issues can be devastating. Let’s say water begins spilling from the bottom of the machine – panic mode sets in and you turn the machine off. Even with the machine off, there will still be water inside, meaning you need to carry out a little troubleshooting. Draining the washing machine can be done using the screw cap at the bottom, but the issue may be the drainpipe – is it clogged?

How Do Washing Machines Drain?

Washing machines may look simple on the surface, but a lot is going on under the hood. After your machine has finished cleaning clothes, a pump kicks into action and starts removing water from the drum and into the drainpipe hose. Typically, this pipe has an upwards curve into a standpipe. When everything is in good working order, water travels up the pipe and into a standpipe, which is responsible for taking the wastewater from your home and into the sewer.

If there is a problem during this process, the water can travel back up the pipe and enter your home, which can cause extensive damage. As well as this, a standpipe that’s not properly vented can release toxic gases into your home. You can read on here to find out more about properly vented drains.

What Equipment Will You Need?

To successfully drain, a washing machine will need the following components:

  • P-trap. This puts a wall up between toxic gases and your home, by making sure water doesn’t sit stagnantly.
  • Cheater valves. Allows air into the flow of water – check state building laws to make sure these are allowed in your area.
  • Venting standpipe. A straight pipe typically runs up through the roof and releases harmful sewer gases.
  • Standpipe. Between the washer and the drain, this horizontal pipe is angled a quarter-inch foot in the direction of the drain.

Preventing Machine Drain Overflow

As well as causing damage to your home, an overflowing drainpipe tends to stink your house out, making it almost unbearable. Luckily, by carrying out regular maintenance tasks and following simple best-use practices, you can prevent machine overflow. For example, removing the drainpipe regularly and cleaning it will prevent detergent buildup. Additionally, using the correct products will help to keep the drain clear.

Additional Maintenance Tasks

Venting your washing machine isn’t the only plumbing maintenance task you need to learn about. There are many pieces of equipment in the home that utilize drain systems. For example, if you have a dishwasher, similar maintenance tasks need to be carried out. Additionally, homeowners with a garbage disposal will need to clear out the p-trap to prevent the buildup of waste. Many of the draining systems must adhere to various state building codes, which is why it’s a good idea to have a professional carry out repairs.

To avoid allowing water and noxious gases into your home, it’s important to ensure that your washing machine drainpipe is properly vented. Additionally, regular maintenance should be carried out to avoid clogs.
