A hundred dollar wire

The replacement part came in on time and worked perfect. That said, $100 for a 6 inch wire that replaces a wire that broke with no explainable reason is sort of hard to comprehend.

Michael K. (Macungie, US)
Perfect Fit, Thinner Cord

This works perfectly, and the sensor end even fits better. The cord does not seem as tough as the original ribbon cable style one, though, so be careful with it when installing!

Thank you, Michael, for your business, and for taking the time to write this review !
We look forward to helping you again soon.
Take care and stay safe.

Aquamaster and WaterBoss Flow Sensor/Cap Assembly

Updated version of the original WaterBoss sensor. I live in the Dominican Republic, where I house my water softerner in an exterior location, due to that being the entry point for water into the house. Up to this point, I have not had to purchase replacement items, as my water softener was on warranty; - wouldn't you know it, as soon as the warranty period ended, something had gone into the unit through the rear and decided to eat the sensor and power line to the computer. As I have to purchase items from either the States or Canada and have them couriered here, I was pleasantly surprised to come across the WaterStore's item. The price was fantastic and offered free shipping in Canada. Fortunately I had a friend who was travelling here days after I ordered the item. Expedient shipping enabled it to arrive in plenty of time for my friend to bring it down. As said, I was extremely happy with the item, as it had a longer sturdy ribbon wire, whereas the old was just three miniscule wires that was virtually impossible to reconnect, as once cut, there was insufficient room to reconnect. Now if WaterStore has a seal that could be used to cover the back piping / entrance of a WaterBoss 700 that would be a bonus. Great experience, I will be a return customer for any future needs.

I’ve been throwing parts at it for weeks now very disappointed no support never buy one of these ...

We will never buy a water boss softener again! I’ve been telling my friends the same!
