I have 2 /12 acres in central california. I bought the house 12 years ago and moved from the city never having a well. The well I have never had a problem except for the controls which looked to be original. The house was built in 1976 and the flex conduit had been there so long that the insulation/outer coating had all but disappeared. The franklin box had no readable information on it so I called franklin and described it to them. They came up with the type/size it was and I replaced it with a new 3 hp franklin with a magnetic contractor and replaced all the conduit. The old box had caps that would go out about once a year baking i n the sun and the pressure switch would have the contacts go bad about every 9 months. No problems now at all with the control box. I have no idea what size pump or type I have except that the control box was sized for up to 3 hp and the pipe to the pump is 2". I have never had a problem with water. Turn it on and it will come out - never running out. The water is hard (Very) and in this area there in H2S in different areas although I got lucky and have none or very little. I replaced the shut off valve on the galvanized tank and looked inside the tank expecting a lot of sediment or sand but there was very little. The previous owner had 5 acres of walnuts and used this well to water them. I have been planting more and more trees which are watered with drips. Up to about 125 trees now plus the lawn in the front and back. I had ran 1 1/2" line out to the middle of the back half and used 1" sprinkler valves with 5/8" drip with about 25 trees on each zone. I had pressure problems with the smaller line the previous owner had ran, but with the 1 1/2 I have good pressure. Now for the problem.
The house is about a 120' feet from the well and it was run on 1' line and the flow and pressure in the house are less than desirable. I'm in the process of installing a 2" line to the house from the well and for the watering zones I have in front. I believe this well help me flow and pressure problem at the house like it did in the back half and I was trying to find another larger galvanized tank to reduce the cycling at the well. (Every coupe minutes.) When I came across the CSV. Knowing that the cycling shortens the life of the pump this sounds like what I've been looking for. Especially knowing that the pump has been in there for 12+ years and maybe since 1976.
1. Will a 2" threaded CSV work in a application like mine(Since the line from the pump is 2") with a conventional water tank reducing cycling during irrigation and helping keep constant pressure or better pressure at the house?
2. How would it be installed? Pump-check valve (above ground)-2" CSV-galvanized water tank inlet with pressure switch-2" water tank outlet-to manifold out to house and watering stations?
3. Should the check valve be replace at the same time? (Works good now as far as I know just preventive due to age.)
4. Would an electronic pressure switch be preferable to the 40-60 one I have now? (It works fine now with the magnetic starter control box)
5. Would adding the pump sensor/monitor be a good idea also?
6. Do I need a small pressure tank also with the galvanized water tank? (I've had no problems it - Tank is 8' from the casing)
7. Last do I or would I need to check the pump for a shroud? I'm trying to avoid having to pull the pump for no reason. I did drop a weighted string down the casing once and it was still dropping past 175-200' with water showing up around 75'. Don't know if that helps on anything. I would hate to burn up the pump by installing a CSV and the house not using the 5 gallons a minute. The irrigation part - I'm sure there wouldn't be a problem but I don't irrigate 24hrs a day.
Yes a CSV would keep the pump from cycling and give better pressure to the house. And yes a CSV will work with a galve tank, but there are some considerations. First you need a brass bleeder orifice in the well, not a rubber one. Next cycling is now what charges your tank with air, so when the CSV reduces or eliminates cycling, you may not get enough air charge. Lowering the bleeder orifice will give more air when the pump does cycle, or you can use a compressor instead of the bleeder. You don’t want to run air from the bleeder through a 2” CSV, but all you need is a 1.25” CSV, and they work fine with a bleeder. You won’t “burn up” the pump with a CSV, BECAUSE it has a 5 GPM minimum. That doesn’t mean you can’t use less than 5 GPM. Just that the pump will cycle slowly when you do. You probably don’t smell the H2S because you have a galve tank. Changing out to a bladder tank is probably not a good idea. Since your pump seems to be holding up well, I would just turn up the pressure switch a little for better pressure in the house, manage the sprinklers to reduce cycling, and leave well enough alone. You can always fix these things and add a CSV when the pump has to be replaced.
