Ideally you should extend the plumbing to the appliance, for both water supply and drain waste. But if absolutely necessary you can extend your waste drain hose to a maximum of three (3) metres, providing the use of the correct bore size, type, and quality of hose, and suitable joining pieces are employed.
Mike Casey, a licensed plumbing contractor and co-author of Code Check Plumbing, responds: Most dishwashers come from the factory with a 6-foot 6-inch drain hose, and nearly all manufacturers allow this hose to be extended to a maximum total length of between 10 and 12 feet.
Is it OK to extend washer drain hose?
Do not install the drain hose with the end lower than 29.5 inches (0.7 m) or higher than 96 inches above the bottom of the washer or more than 60 inches (1.5 m) away from the washer.
Connect the Hose: You may need a dishwasher connector fitting to make the transition from the hose to the garbage disposal. One end of the connector attaches to the smaller drain hose, and the other end has a larger 7/8-inch fitting that attaches to the garbage disposal.
What is the maximum dishwasher drain length?
Do not exceed 10 feet distance to drain. Do not connect drain lines from other devices to the dishwasher drain hose. Dishwasher must be connected to waste line with an air gap (not supplied) or 32″ minimum high drain loop, depending on local codes and ordinances to prevent back flow into the dishwasher.
Can you extend a drain pipe?
A drain kit is designed for a typical drain, and some drain situations are not typical. A straight pipe that is too long can be cut, but one that is too short must be extended. All the parts you need to extend a drain pipe can be purchased from any home improvement store.
How do you splice a dishwasher drain hose?

Can I tie washing machine drain into sink drain?
Just like the dishwasher, a washing machine’s drain pipe can easily be modified to drain into the sink.
Why does dishwasher drain hose need a high loop?
Without a high loop, dirty water from the sink can collect into the drainline and even back up into the dishwasher. This can cause odors and allow waste water from the sink to enter into the dishwasher.
You cannot combine the hoses and you will require a sepreate drain connection, preferably to the other side of the sink to make it drain correctly. You may even have to install seprate P-traps if they discharge at the same time and overwhelm the drain.
Should a dishwasher drain into the garbage disposal?
A dishwasher does not have a separate drain as part of your home’s plumbing system. Instead, it drains through the disposal. That includes any food debris washed off the plates and bowls during the cleaning cycle. When the disposal is draining slowly or is clogged, those problems can affect the dishwasher.
Can you connect 2 drain hoses together?
You can’t just T-them together to go into a side feed on a U-trap because the pressure in one will cause some of the drain water to flow into the other machine. You can hook both outlet hoses into one downpipe with a U-trap at the bottom, because the air gap at the top will isolate the two flow pressures.
Can I run my dishwasher twice in a row?
NO. Dishwashers are not designed to be run twice but in just in one pass they will be able to clean all dishes.
Is high loop for dishwasher safe?
If the drain becomes clogged, the waste ideally would back up through the garbage disposal and into the sink rather than back into the dishwasher. Though a high loop is a classic and effective method of backflow prevention, it is not as safe as an air gap. A high loop cannot assure back siphonage prevention.
How much does it cost to put a high loop on a dishwasher?
As seen in the above video, It can be installed for free. The real cost for this type of install is 5 minutes of your time and less than $2 for the screw and a clip or zip tie.
Is a high drain loop or air gap better for dishwasher?
Air gaps for your dishwasher are a safer and more effective option than high loops. They are mounted above the sink to prevent wastewater from entering the dishwasher from the drain. This separates the hose so no water will be able to get through. This creates a gap between the dishwasher and garbage disposal.
Can a kitchen sink and washing machine share a drain?
If you’re joining a washing machine and kitchen sink on the same drain, you may be able to vent them both with a single vent if they are close enough together. If not, you can connect their separate vents before they tie into the main vent stack.
Can a washing machine and bathtub share the same drain?
You can tie in a shower and tub drain to your washing machine drain as long as there is a vented pipe tied into the drain to keep the flow moving along fluidly.
Does a dishwasher drain hose need a clamp?
No matter if you’re connecting the dishwasher hose to the garbage disposal or the drain assembly, for this project you’ll need pliers, a bowl, a nut driver and a stainless-steel hose clamp.
