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.
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 you splice a dishwasher drain hose?
Splicing Plastic Dishwasher Pipe: Family Handyman recommends using mission couplings and plastic couplings to splice drain pipes and says these can work on cast iron, ABS and PVC. Mark your cutting points on the old pipes, making them 1/2 inch larger than the replacement pipe.

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 2 sinks share the same drain?
In most cases, you can easily adapt the supply and drain pipes to accommodate two sinks, using tee fittings, special valves, extension pipes and hoses. You may have to vent each sink separately, though, depending on your local plumbing codes.
Anytime your drain goes up and down more than once, you have a double trap UNLESS you place an air vent between the two traps that vents ABOVE the drain inlet. The double trap causes drainage issues because air becomes trapped between the two traps, and air is lighter than water.
Can you daisy chain water hoses?
You can connect multiple hoses, but just make sure you consider that the pressure towards the end of the second hose will be slightly less than closer to the water source.

How far can you extend a dishwasher drain hose?
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.
Does a dishwasher drain need a high loop?
The high loop is necessary for 2 reasons. The first is to ensure proper drainage of waste water during the drain cycle and prevent siphoning. The second is to prevent contaminated water from the garbage disposal or sink drain from back-flowing into the dishwasher.
Does dishwasher drain hose go above or below trap?
The dishwasher drain must be connected before the P-trap, not after it, which is what was done here. With this improper installation, sewer gases have the potential to come back into the dishwasher.
Air gaps are the most effective means of preventing your drain from cross-contaminating your dishwasher with waste. If you want to protect your dishwasher from flooding with contaminated water, you need an air gap. Dishwasher air gaps are also required by plumbing codes in many locations.
Can a drain hose be too long?
Make sure that the drain hose is not stretched, pinched, crushed, or kinked. Do not install the drain hose with the end lower than 29.5 inches (75 cm) or higher than 96 inches (244 cm) above the bottom of the washer or more than 60 inches (152 cm) away from the washer.
Why does dishwasher drain hose need a high loop?

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.
Is a dishwasher air gap better than a high loop?
An air-gap is essentially the same as a high loop however it extends above the counter top and has a gap in the piping. In the event of a backflow there is no possible way for the dirty water to flow into the dishwasher.
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.
