I have a shallow well that I just got operating correctly, for the most part, but there are some issues.
One issue that I have is some sand/silt upon initial start up. I installed a sediment filter and the irrigation system works well enough that my lawn is green once again. One thing that I have noticed is that my new pressure switch will not always operate, and I have to take it off and clean out the silt that I find. Since I didn't install the filter before the pressure switch, I see myself re-plumbing the output to place the filter before the switch/tank. Can I get confirmation that it is the right thing to do?
I have also noticed that my new check valve (Home Depot-Brass) doesn't always close/seal correctly, allowing the system to loose prime (I blame residual silt). Are there any check valves out there that are better than others? Could I replace the spring with a slightly stiffer one to help seal after shut down? Since I believe I will be re-plumbing the pump output, should I also re-do the input and mount the check-valve in a verticle instead of horizontal direction?
Here's my last issue, the system is for irrigation only, and the sand/silt only appears for a minute or two, if at all, upon pump start up. My thought is to install a new Zone 1 before the sediment filter, and use it as a 3-4 minute "Dump" when it begins pumping. This would allow the sand/silt to be pumped out without the possibility of clogging the filter, which can continue to catch the little stuff while watering. I guess one downside is a stuck open Zone 1 (due to the crap I'm trying to get rid of) and less water for the rest of the Zones. Good idea/bad idea?
Thanks in advance,
