Connecting Washing Machine Waste Pipe to Sink

Running waste from the washing machine and dishwasher in the same waste pipe means fewer unsightly pipes leaving the property. This hack is useful if the pipes exit through a wall before going into the ground. It can help to eliminate any extra source of leaks that can be a problem at any point. Have a low water pressure, see our list of best kitchen faucet for low water pressure.

There are two ways to connect the washing machine waste pipe to the sink.

• Through Splitter

This is an easy option in which you leave the existing waste in place and connect the other two wastes to a splitter. This process needs less plumbing experience and also doesn’t create any mess.

• Through double-spigot trap

The waste leaves your property through a U bend just like the one in your toilet and beneath the sink. It has a piece of vertical pipework that leads to a trap or U bend. You can use a double spigot trap to replace the vertical pipe. There are two connections in the double spigot, which allows connecting one to the dishwasher and the other to the washing machine.

Installing Washing Machine Drain Hose

The function of the drain hose is to funnel the waste from the washing machine into the ground. Remember, washing machine outlets are typically universal, with similar connections. You will find the same fitments with most washing machine drain hoses.

Also, many hoses simply screw on and are made so that tight connection is convenient even for those who would struggle. If there is a jubilee clip, make sure to use it for an absolute water-tight fit.

A washing machine needs three different types of connection for proper functioning, including water, electrical, and waste. If a washing machine is placed near the sink, you can easily connect the waste pipe to the sink.

To add a washing machine waste pipe to the sink, you need a spigot connection which means that pipe work taking one incoming pipe can take two.

Essential Code Problems to Remember

Remember, the output from your washing machine is under pressure, and a typical 1 ½ inch sink P-trap assembly is not good big enough to handle it. For instance, if you connect the washing machine drain hose to your sink drain before the P-trap, the complete drain (along with the trap) must be constructed of a two-inch pipe.

You can also construct an auxiliary P-trap as an alternative for the washing machine and vent it using the air admittance valve. Then, it can connect to the waste pipe into the sink trap empties with the help of sanitary tree fitting.

If you permanently connect a washing machine drain hose to the sink drain, there may be backflow issues. You can prevent it by creating a high loop in the drain hose that rises up above the flood rim of the sink before it connects to the sink drain. Make sure to check it as it may not be legal in your area.

Useful Tips to Prevent Clogging

To reduce the chances of clogged washing machine pipe, place a durable wire mesh lint catcher at the end of the drainage pipe coming out of the machine. It will help to catch lint and debris coming out of the washer and minimize the chances of clogging the pipe.

Don’t forget to wash the link catcher on regular basis to keep the water flowing out of the washer flawlessly.
