Irrigation / Choosing CSV and System Configuration
« on: June 04, 2021, 05:29:39 PM »
Hi
I am revamping a 20 year old house and irrigation system. It has a few big issues one issue is during the winter months the water becomes very dirty looking from colloidal clay not able see much light through a glass of water. During the summer irrigation season sand is a small issue fouling / damaging valve diaphragms. I am adding filtration to address the above issues.
I also want to add a Cycle stop Valve and would appreciate some help choosing.
I don't know the exact pump model.... But It is a Franklin 1HP Pump and draws 9.1 Amps when running irrigation. Water static level in well is about 70' Pressure Switch is configured for 60LBS Start and 80Lbs Cutoff Two Pressure tanks with a combined draw down capacity of 40Gal at the pressure band it is configured for. 1-1/4" PVC line from the well. With Lots of Elbows and Tee's and a mixture of 3/4" PVC The Irrigation system can sustain about 24GPM at 40LBS. I am hoping that with Proper sized piping I can sustain 24GPM or a little better with better pressure.
So The CVS1A seems like a great choice but its max flow is peaked at where my peak is and I hate to have it becoming a limiting factor. the The CSV1's seem to be sensitive to dirt and may leak a little over time and i hope not to have dampness in the well house.
Qestions:
If the CSV need a pre-filter what size mesh is needed to protect them from the sand? Will the colloidal clay be an issue?
What CSV valve is recommended?
Thanks in advance
