So I've been thinking...
As it stands now, my drain pipe is an inverted-J, presuming to allow for evaporation without loss of flow. Is this a good decision or should I proceed with adding an adjustable reverse bend, resulting in an open-top skimming design?
My thoughts turned this direction while test-fitting the reverse bend PVC
It feels like there might be little difference between the two, yet the open-top would provide a means of stopping flow to perform sump maintenance.
Also, what, if any, beneficial and/or detrimental effects would there be to adding a check valve in the return line? The plus/minus chart shapes up initially as:
1) Anti-backflow from discharge line
1) Pressure loss and therefore reduced flow & circulation in the tank
The first "Minus" can be overcome with submerged circulation devices...
My current pump is a Rio+ 1100 rated at 1450LPH (383GPH) — not sure how much would be lost with a 5PSI check valve, but it feels kinda right to accept whatever losses might be incurred vs potential water damage.
My current inverted-J drain has a 3/16" siphon breaker already drilled...
