Descaling a Lay-Z-Spa water pump unit with my own contraption

The Bestway hottub’s water pump must regularly be descaled. It’s not easy to add huge amounts of chemicals to your pool water to have a meaningful effect when you have serious calcium buildup in your water pump unit. So I made myself a contraption.

I remember that somebody made something for this himself too. His contraption inspired me a little bit of course.

I used the tubes from a old Bestway hottub. I just cut them out of the inflatable pool before I disposed myself of the rest. Then I made two holes in a cheap water bucket and I attached the tubes with some rubber and other things to seal them to the holes.

Now I can descale my Bestway water pump unit like how the professionals do it!
