What Plumbing is Required for a Dishwasher?

To install a dishwasher the following things are required: space, a water supply line, a drain line, and a power source. From a plumbing perspective, a dishwasher needs a way to get hot water in and flush water and food waste out. For most homeowners, these requirements are not hard to come by since a dishwasher is located near a kitchen sink. The dishwasher will be connected into the plumbing for the sink to give it access to hot water so that it can clean dishes effectively. The dishwasher will also be connected to an inlet on your garbage disposal to give it a way to drain out dirty water through the drainpipe for your sink. A professional plumber will know how to replace your shutoff valve with a connection give it access to hot water and how to fit a Y-shaped tailpipe to allow the dishwasher to drain properly. Getting these plumbing necessities right the first time is crucial to ensuring that your dishwasher will work properly without leaking or backing up.

If you already have a dishwasher installed, replacing your dishwasher will not be as difficult as installing a new one yourself, but both situations benefit from having a professional plumber do it for you. A licensed plumber has the tools and experience needed to install a dishwasher no matter what your kitchen plumbing layout is or what kind of special circumstances you have. A plumber knows how to work around trouble spots like narrow spacing and tight connections.
