Rodi and well pump short cycling

[Johnd651]

So this is the first time I've ever lived on a well, and have been using the ro portion of the rodi for drinking water, so the consumption rate on the pressure tank is not very high. However, once I start filling the tank up initially, the 150 gal of water will really be 600-750 gallons of water with waste.

Any tips or tricks to keep the well pump from cycling on and off? I have a 150gpd system, so I'll probably be pulling 25-30 gallons of water an hour which is not a lot. I was thinking of trying to only run it when other stuff runs water but there's not much we run long or full blast...darn he and energy star.

Well pumps are designed for this type of use.
They are high grade turbine pumps.
Exactly like the turbine pumps used at gas stations.
The difference is the gas station motors are seald better for obvious reasons, and the turbine material is rated for fuels, where your pump is not.
The point is Franklin makes them and you will be fine.

I am a fueling electrician and have dealt with turbines for 25 plus years.

I also have am on a well and produce hundreds of gallons of RO/DI water.

Just out of curiosity.
What are the Well specifications?
How deep is the well?
What depth is the pump sitting at?
How many gallons per min did it produce when tested?
How old is the pump? Months years decade's?

As you said your being new to a well leeds me to believe that you just purchased the home and this information should have been provided.

Long story... when we moved in 3 years ago we could not find the well, and previous owners had no info. Pressure tank is 20 gallons. Had flow of about 6 gpm out of the tub faucet. Finally found it, was an artesian well that had been close to ground level that rusted the top cover out. We put in an overflow at the pitless adapter into the ditch and raised the casing. Last fall, the pump died. Wife and I pulled it, and found it was a 30 year old 4 wire goulds 5GS07. At that point no one had much locally so we ended up going with a Goulds 7G07, 3 wire. We did try to measure and dropped a weighted line down, ran out of line at 300ft, but we have been told there's an underground lake here. Measured the well pump, found it's sitting at about 200 ft.

Good pump and setup?

I have run my RO/DI on my well for 10 years.

The trickle that goes into your RO/DI is nothing compared to a normal appliance.

I also just ran my RO/DI for a couple days straight in order to fill up a new tank, and I didn't notice any abnormal well noises for that either.

The one thing I would caution is that you would be throwing a lot of water at a septic tank. Keep an eye on that.

Since we have gone through a couple of spring melts we have learned that the pool waste and sump pumps all dump into the septic which causes a little bit of water in the spring. We also learned our leach field is just a single 100ft length of perforated pipe. We have since removed the pool, and plan on moving the sumps out into a drainage ditch. The rodi waste will either go with the sumps or I will just run the waste line to the ditch.

You can water plants or lawn with the RO/DI waste line.

Yeah I got lucky that we have a dry well that was setup to receive clothes washer output. I ran the RO waste line to that.
