Over 100 SIS Ballcocks installed - not one failure

My farming operation has been driven mad by leaking ballcocks.

Because of a tank system, we know everyday the quantity of water that we use or lose.
It has been very exciting to offer my property and our water supply system to help in the development of the SIS Ballcock.
We have been installing the SIS Ballcock since the first prototype, back in 2014. We now have over 100 SIS Ballcocks installed - not one failure or problem.

Part of the dead ballcock graveyard (the brands that didn't make it).

What our customers say

The SIS Ballcock - Stainless, Indestructible, Simple. Half of the water on our 600 cow dairy operation goes through a tank system. We have had huge frustration with leaking and totally failing ballcocks. The problem has now been solved, for over a year, with the installation of a SIS Ballcock.

As a reseller of farm ballcocks, I think we have just had the rug pulled out from under our feet. Hawera Rewinds have just released a ballcock that is SO SIMPLE, it will make you smile. Virtually indestructible, made out of solid 316 stainless steel, you will only need to buy it once.
