Our plumbing currently goes from cartridge filter about 15' horizontal to the gas heater then 15' back to a chlorinator (left empty most of the time) and out to the pool. All this is in our basement; lines then go up and through the sill plate out to manifolds and then to the pool. There's no bypass for the heater. Here's a crude diagram:
Would it be wise to add a couple tees and a valve to bypass the heater like this?

The boiler drain would be added so I can screw on a garden hose to the floor drain and empty the filter container when cleaning the cartridge.
Thanks for any advice.
