Rotors

Here is a unique problem. I installed a system that draws water from our lake as the water source. I have a 100 micron filter installed downstream of the pump (prior to the valves). My Hunter PGJ rotors have stopped rotating after 4 months of operation. On inspection, I noticed the rotor filters are impacted with algae, so much so that the algae has extended through the filter and into the sprinkler gear mechanism. Cleaning the filter did not solve the problem, so the gears must be mpacted as well. Since the rotors are molded plastic, I cannot get them apart to clean the gear assembly.

I am at a loss, Hunter has no solutions for me. Does anyone know of either a solvent I can soak the rotors in to kill the algae without damaing the rotor, or of a rotor on the market that can disassembled for cleaning? I would appreciate any inputs. Thanks.

Consider redesigning the system with Maxipaw impact-type rotors.

You may need a better filter.

Did you use scrubber valves?

This may be the first of many issues.

He maybe needs a better lake. There's only so much glop you can pump into a sprinkler system. Impact heads are for the filthiest water. For small ponds, an aerator fountain can make a big difference.

We need photos of the lake. Good Call.
