    Portable dishwasher vs spray hose
    Have purchased a new portable dishwasher. Kitchen sink faucet has a spray hose. Installation manual says to disconnect spray hose from the faucet and cap the connection. I also had to remove the swivel aerator. I want to keep both the spray hose and swivel aerator. Any suggestions?

    Well you can't keep the swivel aerator. You must replace it with adapter to connect to the dishwasher. All of these that I've seen also swivel. If you remove the aerator on the swivel, will the dishwasher adapter fit onto the swivel?
    Don't understand why you would have to remove spray hose. Perhaps you have misunderstood the instructions. Instructions may be referring to pull out faucets that have a head that allows you to choose between stream or spray.

    I am assuming that you have a faucet with a side spray.

    I agree with Harold. If you have a side spray, then there should be no need to remove it. If you want to keep the swivel, just remove it and install the dishwasher adapter when your using the dishwasher then reinstall the swivel when not using the washer right?

    Thanks for your input. The instructions were clear that if the faucet has a spray hose that it must be removed & connection capped. I believe that this is cover the manufacturer in case there is a leak or burst of the sprayer hose or it's connection to the faucet. This could be problem if one has abnormally high water pressure and/or old spray hose.

    After inspecting the hose, it's connection and running the dishwasher I determined that the water pressure isn't great enough to cause a problem. However, will not start the dishwasher just before going to bed or leaving house. Will wait for wash cycle to complete first.

    Don't understand. The water pressure on a side spray is determined by the water pressure in the house. The dishwasher should have no effect on the spray. Capping the hose would not really change anything. The spray nozzle, when the handle or lever is not pressed is doing the same thing as a cap would do. Capping the spray will do only one thing, prevent you from using it while the dishwasher is in filling. And I can't see how that would affect the dishwasher. I see no risk to leaving the spray. Try the spray while the dishwasher is filling to see if there is any affect. If there is, just don't use the spray during that time.

    Having had two spray nozzles burst and nearly flood my entire kitchen while using a portable dishwasher, I can assure you - it does make a difference. When the portable dishwasher is hooked up and the water is turned on, it creates backpressure on your sprayer hose when the dishwasher is not in a "fill" cycle. This pressure is normally not there - when the water is on, it flows from the faucet unless you squeeze the spray nozzle's trigger. The dishwasher stops the flow of water, but the supply is still on which causes pressure on your sprayer hose. Having the dishwasher hooked up not only puts pressure on the nozzle, it puts -hot- water pressure on it. If you're going to keep the sprayer hose and use a portable dishwasher, make sure you have a hose with a metal sprayer in good condition (plastic ones last maybe a year before leaking or bursting in these conditions), and NEVER leave the dishwasher hooked up with the water on while you're sleeping or away from home.
