Recently I laid the main retic line for a client in Jindowie (a part of Yanchep). I’ve written before about water pressure issues in this part of the world and today we hit the same problem again.
I use Richdel solenoids 99% of the time, but today they wouldn’t seal. They need a certain amount of backpressure and the water being what it is up here I just couldn’t get them to work.
I changed them for Hunter PGVs and they worked fine. I’m not sure why Hunters will operate with the lower pressure, but they seem to be the answer when the Richdels fail.
Lucky I had 4 onboard to substitute!
