We're closing in on having our coping and decking completed, at which time we're also working up a drainage plan. The plan is to configure what is essentially a 40 sqft/80 cuft (600 gallon) gravel drain field out in the yard, and into that field would be the pool overflow, a channel drain from part of the deck so water doesn't pond against a small retaining wall, and the outlet from the filter for backwashing. The 600 gallon field should be sufficient for a standard backwash/rinse cycle, but in the future when I have a need to drain a much larger amount of water I need a way to divert that outlet from the field to a temporary hose I would run out to the street about 120' (uphill) away.
Should I just add a standard 3 way diverter valve on the outlet side of the filter? I would have thought this might be more common but couldn't find similar setups in a search.
Running backwash to the house drain isn't an option (septic) nor do I want to trench a permanent line 120' uphill to the street.
