Pumps, Wells, Tanks, Controls / Re: Submersible Well pump and Radon system

That is about how I had it set before the radon system. With the radon system, the well side only effectively sees 1 fixture that is either full open or full closed, which is the valve that controls refilling the big aeration tank.  The cycle time of this part of the system is pretty long, which meant with the csv installed, the well would fill the aeration tank in about 30 seconds, then continue to run for another 30-45 finally to shut off not long before the aeration tank called for more water. Without the valve, the well runs for about 45 seconds and then shuts off for the remaining time.

Pumps, Wells, Tanks, Controls / CSV1a stuck closed

I have a valve installed that's been in happy use since 2010 on my home well. I noticed today that my pressure on the well side (i also have a radon system that masks the low pressure normally) was very low (~20) and the CSV was whistling as it does when it's near the cutoff pressure. After multiple debugging steps Including removing the internals, light cleaning etc, I determined something was wrong with the valve and removed it from the system. I'm now getting full flow that cycles low to high in about 45 seconds so I know my pump is good (it's only a few years old anyway).

I've now taken the internals completely apart which I didn't do the first time. It was pretty clogged with iron and somewhat hard to slide the valve up and down even after cleaning it out. So the question is, how do I tell if the rebuild kit is really needed, or if there is something else amiss? It seems to me that if the diaphragm wasn't working that it would stay full open not full closed. There was no water on the spring side of the diaphragm and visually it looks fine.

Pumps, Wells, Tanks, Controls / Submersible Well pump and Radon system

« on: December 21, 2019, 06:59:44 PM »

Hello, I've had a CSV1A installed for many years and am quite happy with the results.

Last year I had a radon water system installed (AI Raider 433s) which consists of another submersible pump in a tank along with a pressure tank, switch etc. I didn't change the csv yet but I'm not sure how to make this system work properly. What happens when we call for water is it draws down the radon pressure tank, which will then kick on the submersible in the tank. The tank has enough water to about fully fill the pressure tank. Then the tank calls for water which opens a valve and water rushes in from the well pressure tank. This also has just about enough to refill the radon tank and so it shuts off the intake valve just about the time my well pump spins up.

In all cases of constant water usage except perhaps filling the washer, the well pump turns off not too long before the valve opens again causing the well to kick back in. With the valve set as I had before the radon system, it takes about 2 minutes to fill the well pressure tank before shutting off.

I recently had to remove the valve because it wasn't working correctly (will post separately about this) and with the valve removed, the well pump cycles on for about 45 seconds with about a minute in between when using just the shower.

So, how should I go about tuning this system?

 I've tried to think through how it might work with a csv1a also installed on the radon system which would stop that pump from cycling, but the high and low floats in the tank control the input from the well tank so it's either full on or full off as far as the well side sees. I also considered cracking the bypass so that while water is being used upstream of the radon, the well would see some flow and keep that pump spinning. The problem is when the pump is off, I'm effectively drawing down both tanks in parallel which lets more untreated water through than I would prefer.
