Plumbing Help
 

looking for a 3/4" check valves [plastic type]
or back flow preventer
do you guys know what store carry these parts?
went to home depot and they have the backflow preventer but its copper

How come you need this? Shouldn't be nessisary unless you're inventing something. :mrgreen:

=o)


oh yeah did you open the shop today?
couldn't come over too much snow
and shitty i'm working tom

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. :biggrin:

Christy :)

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)

hole size
 

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.
