Ive never had a problem with my dishwasher hose leaking. I just use a rubber hose, its not even braided. Its been like this for 18years. I replaced the dishwasher myself when I first moved in, but never replaced the original hose from the previous owner. I run my dishwasher every 3rd day so I’m not sure if using it more frequently or less frequently is better/worse for the hoses.
The leaks I have had were with water shutoff valves all over the house…The old style screw-in type shutoff valves are notorious for leaking if you don’t use them most of the time, and seem to fail in the rare cases you actually need to use them to replace a fixture.
I’d recommend for every fixture, waterline, you replace the shutoff valve if is one of the really old screw in type… Replace them with the newer ones that are quarter turn shutoff valves. They aren’t that hard to replace, but well worth it especially on older homes. The worst situation is when you have a fixture that leaks, and you try to shutoff the water line, and the valve itself is broken.
Basically, most valves are compression type fittings that sit over regular copper pipes, so it’s a matter of unscrewing the lock nut, and than screwing in the new valve tight. You’ll know if you screwed up and didn’t install it correctly, because the thing will either fall right off or leak massively.
Also , since my washer and dryer on upstairs, I’ve gotten into a habit of shutting off the water lines when I’m not using the washer, in addition having large drip tray that empties into a built drain. also i have a water sensor that is hooked up to my alarm system.
Also, if you don’t already have one, I’d get a shutoff valve installed on the water line running just into your house. If you have already have one, I’d make sure that it works. Normally, if I were to go on a short trip lasting longer than 2 days, I would just shutoff the water running into the house, and leave the water running to the irrigation systems….Unfortunately, that valve is also currently broken and doesnt shutoff (surprise surprise)…and i haven’t gotten around to replacing it. It’s a little more complicated since I think mine needs to be cut out and welded.
