Thanks Gman for the heads up. I did just purchase the continental hose.
So vinyl hose then 1/2 in. Also i bought the 1/2 in fittings from lowes.
Ya im not sure what the deal was with that hose i had . Could have been a freak thing. I have 5 ppk systems going with 8 to 12 sites each, once 20 sites moved down to 12 sites. All built at different times over a 2 or so year period. Was weird to see the rubber balls.
Other systems have been fine. I dont know, maybe someone was sleeping at the factory an made a Shitty rubber formula?Not sure, other then anything is possible. Just makes sense today to use a food grade hose.... thats all. post some pics when she running. Would be nice to see the thread moving again
