Suction Filters

A fine suction filter from WISY is absolutely essential for every rainwater installation! Increase the safety of every rainwater installation through preventing sediment and foreign matter from being suctioned out of the cistern.

The ball float allows the suction point to rise and fall with the water level and ensures that the water is taken where it is cleanest: just below the water surface.

Value of Filters

The value of this component cannot be overstated. When you ask someone where the water comes out of the tank, the answer is always “from the bottom”. Unfortunately, that is the same answer given when you ask where the dirtiest water is. These devices will pay for themselves by reducing the need to change your cartridge filters. They are a simple, logical piece of a low maintenance rainwater system. They can be connected to the inside of the bulkhead fitting by using appropriate fittings and flexible potable water hose. I have had one installed in my tank for over two years. When someone asked how often it needed to be cleaned, I looked and decided to give it a couple of more years. It is a good idea to examine these parts on a yearly basis.

 

These filters can be easily retrofitted to most installations.
