Hey Jesse,

Why not drill a little hole in the line just before it hits the water in your tank. That way you don't get a back siphon? And it just sort of pees out into your tank while its running.

almost any and all sprinkler, irrigation suppliers will carry a 3/4" pvc check valves, make sure to get the kind that swings from a rubber support, the other ones will slow flow down too much. do you have a delta irrigation near you? or bcg services?

My understanding on check valves is they'll fail..eventually. All you need is a hole for a siphon break (2 holes is better).

thanks guys
really appreciated
i'll do that drilling thing tom don't mind saving few bucks
=o)

How big of a hole do you drill? With my luck I'll end up with a stream that shoots 40 feet.

Cheers,
Al

i'm thinking of drilling 4 1/6" heheh would that work guys?

no, go a bit bigger. algae and such will clog up a hole that small. I did mine 1/4, and I drilled right thru the pipe giving me two holes. This is incase a snail happpens to be sitting on one hole when the power goes out.
