The main reason to have a plumber install a dishwasher instead of making this a do-it-yourself project is to be sure the work is done correctly. People without experience in Plumbing in Portland OR are prone to making errors, especially if pipes must be extended to the location. They also probably don’t know the plumbing codes, which vary to a certain extent by state.
Preventing Backflow
For example, the equipment needs an installation that prevents backflow into the machine. Some states include this requirement in the code.
High Loop in Drain Hose
One method is to install a high loop in the drain hose by fastening the top of it to the underside of the counter top. The sheer force of the water coming from the dishwasher sends it up and over the loop. Not everyone understands this, though, and may install the hose similar to the way a washing machine hose simply drains down into a sink or a pipe connecting with the sewer pipe. The high loop also prevents odors from wafting up, just as the P-joint in drain pipes under sinks is intended to do.
Anti-Siphon Device
Another way of preventing backflow is to install an anti-siphon device with an air gap. This can be completed by professional offering services in Plumbing in Portland OR.
High-End Dishwashers
There is one exception to this necessity. Some of the higher-end dishwashers have a high loop built in, and nobody has to create one or add an anti-siphon device. This must be confirmed before installation or the household will have problems.
Another Advantage
These strategies also prevent water from the kitchen sink from draining into the dishwasher. This is particularly troubling when the water is dirty from food waste and oils, as it sits at the bottom of the dishwasher and creates odors. If somebody runs the machine, that wastewater becomes part of the washing process.
For the average homeowner, preventing backflow can be a challenge, and many don’t even realize this can occur. For a plumber from a contractor such as Clog Busters LLC, getting this part of the installation correct is easy.
