For the Anderson Kantleak with the multi position valve:
Once you mix the solution attach a siphon hose to the fresh water fill (city connection) and the other end in the bucket of solution then put the valve in the winterize/sanitize position and turn on the water pump. This will circulate the solution through the fresh water system. Crack each faucet until you smell the solution coming through and then close that faucet. Do this for each faucet and don't forget the outdoor shower.
Pour the remaining solution in the fresh water tank either through the fresh tank fill or using a hand pump with the multi position valve in the tank fill position. Fill the fresh water tank and let it sit for 3 to 4 hours. Drain and rinse.
A couple of notes.
While running the solution through the system the water pump will not turn off. This appears (operative word) to be normal for this system.
I keep the water heater by passed. The chlorine concentrate is high and I prefer not to run it through the water heater. I rinse that out through the drain using a small wand.
Here is the info on the Kantleak. The winterize/sanitize instructions are incorrect in that they say the system first sucks the solution into the fresh tank. It doesn't happen that way.
