| | Re: Drain from pressure or suction side?
If "better" means faster, then I would put a two way valve, with one leg going to the usual filter output in the tank, and the other to a drain line outdoors to a flower bed. If "better" means less prone to doing harm, I would put that two way valve in the canister filter inlet line, with one leg going to the inlet pipe in the tank, and the other leg outdoors to a flower bed. (Turn off the canister filter if going this way).
