Got burned on a $420 tankless descaler kit for my restaurant job, and it's still sitting in my van
Last month I bought a $420 tankless water heater descaling kit because a guy at the supply house in Sacramento swore it would cut my flush time in half on the big commercial units. Used it on two jobs at a diner downtown and the pump started leaking gray water all over the mechanical room floor, so I went back to the old bucket and vinegar setup. The kit is now riding around in my van behind the seat, still in the box, and every time I see it I get annoyed. Has anyone found a descaling pump that actually holds up on restaurant jobs, or should I just keep doing it the slow way?
That line about the pump leaking gray water all over the mechanical room floor got me, because I used to wave off the cheap pump warnings and figure a bucket and vinegar was for old-timers who did not want to spend money. Then I watched a guy run a proper flush pump with a flow gauge on a big commercial unit and it pushed through in about 40 minutes what took us close to two hours the slow way, and the vinegar bucket never gets scale out of the bottom of the tank anyway. What changed my mind was seeing the flush water come out clear on the first try instead of us guessing when it was done. So now I am on the side of buying once and buying the right pump, just not a $420 kit that comes with a bunch of stuff you will never touch. Get a pump rated for hot water and continuous run, add your own hoses and a bucket, and you are into it for a lot less than what that supply house charged you.
