Adirondack Pond - I don't think it will work. I recall speaking w/ the Ponddoctors guys (Doug I believe) - and I recall he said use a device like that on the inlet side.

When we did my pond last year - my brother in law mis-understood and made a home made y valve for the outlet side - it didn't work. There's no suction on that outlet side. DOesn't do diddly.

Which is why we went & got a brine tank & did it that way - takes way too long.

Cheesy did it the right way - but w/ the quick couplers he has - I don't know what challenges that provides for one of the y connectors
