My pool is 8 years old and i've replaced a lot of parts this spring. Stumped on what to replace the Ortega spring check in the spa return line with. The obvious choice seemed to be a Jandy 90 deg. spring check except it's not recommended for the flow direction. I have room to mount a straight connection vertically but once again Jandy shows flow down installation as a "wrong" on their installation instructions. Without this check my spa drains overnight enough to expose the plaster. I did install a new spring and seat but the body itself is worn so it won't seal with out a lot if silicon grease. Any ideas.
