You'll have to run a vert line like you mentioned with a siphon break and "T" it off where you want your water level...then if an outage occurs you will only drain down to the siphon break... as far as the canister goes, as long as you have some shut off valves near the canister and you trust your plumbing you can go directly from the tank to canister...IMO of course...Ramesh;2934388; said:Yes I understand, one is for a canister filter the other is for a sump.
The canister may have to have the same setup as the sump, where I have a pipe running from the drain up vertically up to the water level with a siphon break and then back down to the sump tank.
I have though about the power outage issue for the sump but thought the closed system of the canister would be fine but I am open to any advice and experience.
Didn't the builder suggest some overflow boxes, for inside the tank, and bottom holes?
