Help!!

I service a HOA that the irrigation system is on a well. I am constantly having spray heads that the filters are stopped up. Most of the spray nozzles Hunter Pro sprays and I have tried some MP Rotors. I will remove the nozzles and they are covered with dirt/sand. I will turn the system back on with a nozzle removed and I will get a clump of dirt shoot out of the head. What can be done about this? Is there a filter that can be placed on the pump? What other suggestions do you have? Thanks

Sounds like the pump guy and the irrigation guy did not get their numbers straight. I'd call for a pump-down test and then do a survey of the zone demand from the system. It could be a failed well, but I doubt it.

I guess not. I had nothing to do with the install. Could you explain what the pump down test would reveal?

A pump-down test will indicate what the well output is in gpm/psi. It will,, as importantly, register the re-charge time of the well. With those criteria, a proper survey of the system should be done to see if the irrigation has exceeded the parameters of the well. Adding a clock with delay in between stations/programs may help, as will () splitting up the zones. Something tells me the system is jacked.

Of course the well water can be filtered. All well water should be filtered. Sprinklers are usually assumed to be using clean city water, and you must use 80 or 100 mesh strainers in the supply, in order for the solenoid valves to operate properly, before you even worry what the sprinkler heads require.

Depending on the quality of the well water, filters may be needed. That being said, who is going to be responsible for checking and cleaning the filters? RB did make a pretty cool scrubber/filter that was self-flushing, I used them to great success. I'd still have a pump-down test done before looking like a dipwad when it still failed to perform after convincing the client that was all they needed.

Mike I mean no disrespect, you are very knowledgeable on many things. But, the wells you are familiar with perform vastly different than the ones I work with and perhaps other people too. I don't think you should be so quick to judge and cast broad statements about every well in the country. Most of the sediment problems that I have here are from rusty old steel casings, not drawing down the well.

GM, while you are correct, the OP did state clogged filters due to dirt and sand, which suggests demand is exceeding the wells recharge rate.

Which is all I meant to point out. Thanks, sonny. Too many posters seem to forget that "we are not at the site!", we have no idea of local conditions and our posts can only come from our experience with like-problems.

Ok......I had some time to spend at the HOA. They called the well installer and he states that the well is producing "crystal clear" water at the well. The heads and filters that I replaced a few weeks ago seem to be doing better. I noticed that all the zones have 2" water lines and valves. The zone I am having problem with is a 1" valve. Could this cause the problem? The pump is cycling on and off a lot and the spray from the heads is terrible when the pump is off. So I had the idea that if I could combine two zones that would help to keep the pump running. I simply put two wires under one station, and that seems to keep the pump running and the spray heads are doing better. Is this bad? I know that actually combining the zones with the same pipe would be better but I was desperate to keep some pansies alive while we have some 70 degree days. What do you guys think? Any more suggestions?
