Hello… I was told by a plumber that it’s better to have a shut off valve for a new dishwasher put in the basement of the house rather than right under the kitchen sink next to the dishwasher. The plumber is supposedly a master plumber. Can anyone please tell me which is best?? The dishwasher is in place with the soil line attached… the only thing left to do is hook up the water supply. Thank you!
I would install the shut-off valve under the sink, no question! More than likely, a dishwasher shut-off valve in the basement would be up at the floor joists. If you ever had to get to it fast, you’d have to scramble for a chair or a ladder first to reach it.
The only problem with putting it in the basement, is its assumed to be in the cupboard as thats the standard way its done. When you move on, the next folks have a problem and spend 10mins trying to find the valve to turn off the units water supply
