Worked and I'm satisfied.
Size: 1 Quart with Standard Hoses
Worked well. All the connectors were correct for installation. Nothing extra needed but a screw driver and wrench. It cleaned plenty of deposites out of my heater. Good quality hoses and pump IMHO. Seems like it'll last many years.

Doing it yourself is much cheaper than having someone come to the house and having it done.

Good but bucket lid is tight
Size: 1 Quart with Standard Hoses
Good product, effective. Way better than paying plumber $400 per unit. However the bucket lid was sealed tight, so I had to use a box cutter. I know the instructions are to use a quarter to pry it open, but that didn’t work for me. Maybe I have weak fingers.

Easy to flush your tankless water heater with this kit
Size: 1 Quart with Standard Hoses
A great kit to flush your tankless water heater with easy to understand instructions. Plumbers typically charge around $200 to do this service with a recommendation that your tankless water heater gets flushed once a year. Save yourself some money and do the service yourself. The kit has everything you need. ... show more
