Pomivalni stroj na vikendu.

I've heard different reasons for why an additional loop is required under the sink, so I decided to contact the manufacturers directly.

I sent out an email to eight dishwasher manufacturers, asking them this question:

"A high loop is required on the dishwasher drain in the installation instructions for all of your dishwashers. What is the purpose of this? Doesn't the high loop that is incorporated in to the side of the dishwasher achieve the same thing? Any insight or commentary in to this matter would be greatly appreciated."

Here are the responses I received:

Kenmore: "The high loop or air gap must be used to prevent potential backflowcontamination of the dishwasher. Local plumbing codes generally dictate the requirements in your area. Section 807.4 of the Uniform Plumbing Code states: "No domestic dishwashing machine shall be directly connected to a drainage system or food waste disposer without the use of an approved dishwasher airgap fitting on the discharge side of the dishwashing machine. Listed airgaps shall be installed with the flood level (FL) marking at or above the flood level of the sink or drainboard, whichever is higher, or separately trapped with the airbreak located on the stand pipe.

GE: "If an air gap is not required, the drain hose must have the high loop from the floor to prevent backflow of water into the dishwasher or water siphoning out during operation."

Bosch: The high loop in the drain hose of your dishwasher is to keep water from settling in the hose if it were hanging down any lower or horizontally. This keeps the drain hose dried out and keeps any odors from backing up into the dishwasher.

Viking: In testing our dishwashers, we have found that the additional high loop in the back of the dishwasher is required for proper draining of the water. We have seen when this piece is not applied that over time the consumer will have issues with the water back up and causing issues with proper drainage and water pooling in a particular area.

To summarize, the reasons for the high loop are to prevent potential backflow of water in to the dishwasher and to prevent improper drainage of water. Even though dishwashers come from the factory with the drain looped up high against the side of the dishwasher, this is not an acceptable substitute for the high loop underneath the kitchen sink. In Minneapolis, the lack of a properly installed high loop under the kitchen sink requires repair for their Truth-In-Sale of Housing evaluations.

Če ti bo zmrznil, se poslovi od njega.

To si lahko brez skrbi, znam izprazniti vodo iz njega in ustrezno zascititi.

Pozdrav

Ne vem točno, kakšna je konstrukcija pomivalnih strojev, samo, ali ni tako, da na izhodu ni nobenega ventila, samo črpalka za praznjenje? Ne bi potem voda konstantno odtekala iz stroja, če bi bila odtočna cev prenizko?
