Is There Suppose To Be Hot Water Ran To A Dishwasher?

The answer to this question is yes, many people think that the dishwasher element heats up the water and it does to some degree but also using a hot water feed to the dishwasher will save the actual element from being replaced sooner then expected.

There is many arguments however that the dishwasher is supposed to be hooked up to the cold water, and many plumbers will want to hook it up to the cold water as well, but the fact is that the dishwasher does need a hot water line so that it can run properly.

The hot water supply for the dishwasher can come from the same line or pipe that feeds the hot side of your kitchen faucet.  There are two ways that you can tap into the hot water supply under your sink.

The first way is to use a saddle compression valve and tap into the line, or you could pipe in an actual tee with a valve. The latter of the two is the best way as you will want to have a more secure connection. Saddle valves are great for basements and areas that are not disturbed to often Vs a kitchen sink area that receives a lot of traffic.

Make sure that your water heater is also set at the correct temperature to get the maximum results from your new dishwasher.
