Frequently Asked Questions / Re: Can I use a Large Pressure Tank with a CSV?

« on: February 16, 2015, 08:00:25 AM »

You can use as large a pressure tank as you want with a CSV. However, when you are using water the CSV makes it go right past the tank, straight to the faucets. It doesn't matter if it is a 1 gallon or a million gallon size tank. The only time the water in the tank is used is when the pump is off and you are using something small like washing a toothbrush or filling an icemaker. When you tank a shower or use any large amount of water the CSV just keeps the pump running steady with water going right past the tank.

Pressure tanks are not a reliable way to store water for power outages. A 40 gallon tank only holds 10 gallons to start with, if it happens to be full when the power goes off. Murphy's Law says the pressure gauge will always be at about 41 PSI when the power goes off, so there will not be any water in the pressure tank.

A couple of 5 gallon jugs of water in the closet is the best way to make sure you have some stored for emergencies.

Pumps, Wells, Tanks, Controls / Re: Is a CSV right for me?

1 1/4" and 1" CSV's can be installed as far as necessary from the pressure tank. As long as the CSV is before any water lines that tee off or the pressure tank, distance doesn't matter. You can install the CSV in the well or at the well, and the pressure tank can be several football fields away, and it will work fine.

Pumps, Wells, Tanks, Controls / Re: Unsure of well pump and depth - is it possible to use CSV without knowing this?

« on: January 26, 2015, 06:56:06 AM »

I am 90% sure you can use a CSV with that pump. But it is best to have at least a little info on the pump, just to be sure. If you can't find any info on the pump just do a bucket test from the 1" hose and see how many GPM's it will make. Then if it is a 230 volt 2 wire pump with no control box it is 1.5HP or smaller. 115 volt means it is no larger than 1/2 HP. If it is 3 wires with a control box, the box will have a tag that tells you the horsepower. If these things don't tell us what we need, a simple clip around amp meter reading while running the 1" hose of water will let us know everything else we need to know.

The on off pressure are done by the pressure switch. Assuming you already have a 40/60 pressure switch there would be no other adjustment necessary except to set the CSV at 50 PSI.

The CSV1A is the best replacement for what you have.

One adjustment bolt. Turn it until the shower is running at a steady 50 PSI and your done.

Since you say "there was no improvement" I assume the pump was still cycling on and off?

The principal of the Aquagenie and the CSV are the same. Although the bypass of the CSV is more dependable. Sounds like whoever installed it didn't know how to adjust it. It is not that hard but for some reason people will tighten on the bolt, which makes the valve work like a piece of pipe. Loosening on the bolt makes the valve work.

Plumbers and pump installers will try to sell you what they make the most money on, which is the variable speed pump by a long shot. They are expensive, short lived, and greatly shorten the life of the pump as well.

They can't make any money selling a $63 or a $200 CSV, especially because it will make the pump last 4 times longer than normal.

The 7 GPM will work from quite a bit deeper than the 8 GPM pump.

Just being set at 375' means your pipe is seeing 162 PSI. That 8 GPM, 1HP can build 207 PSI, which is what the pipe will see with a CSV attached. This is OK because the burst pressure of that pipe is 2 to 5 times the rated pressure.

I think your real problem is if the well pulls down to 375', the pump can only build 45 PSI and won't be able to reach the pressure switch off at 50 or 60 PSI. Even with a water level of 325' that pump can only build 67 PSI, which really to close to run a 40/60 pressure switch.

Sorry I missed this in September? The 30 PSI loss across the filter is your biggest problem. Even with the CSV holding a steady 68 PSI, you are only getting 38 PSI through the filter.

I am also assuming the outside faucet is a frost free type? Those hydrants can let out 20+ GPM, which is why your pressure drops to 3 PSI as you only have an 18 GPM pump.

Applications / CSV125 Installed in the Well

« on: December 10, 2014, 11:06:57 AM »

CSV12550-1 installed in the well below the pitless. 4.5 gallon size tank in rectangular valve box. Pressure switch and gauge in 6" stub casing under PVC cap. Shut off valve to house in little round valve box on the right.

Up to 2HP, 25 GPM pumps

In areas where the frost line is not very deep, the pressure tank and switch can be installed in shallow valve boxes. This makes for a complete water system installation without having any equipment installed inside the house or a building. This set up also means you can tee in to the underground line between the well and the house. You can tee to the garden, a barn, or even multiple houses anywhere you can get to the underground line.

Open Loop Geothermal Heat Pump / Re: Supply House with Geo Discharge Reduces well pump size, saves big

« on: December 09, 2014, 04:26:33 PM »

The 80 gallon pressure tank prior to the heat pump always caused a bit of a problem. Many times the house would use enough water to lower the pressure and empty the pressure tank while the heat pump was also running. Then when the water in the house was turned off, the pressure tank would be refilled. This starved the heat pump and it would freeze up and shut down.

After replacing the 80 gallon size tank (25 gallon draw) with the Pside-Kick kit and the 4.5 gallon size tank (1 gallon draw)the heat pump no longer starves for water while the pressure tank is refilling.

The pressure tank cannot be installed after the tee to the heat pump. Water cannot go backwards from the tank through the heat pump, and the heat pump will not work until the well pump is started.

Replacing the big pressure tank with the small tank solved the problem I had with flow through the heat pump when the pressure tank was refilling. I am very happy with the way the system works and I only need a 1/3HP submersible to run the house and the heat pump.

Update December 2014

In a recent phone conversation with the engineers on these projects we found that the owners of the concrete plant and the bottling plant have had no problems and still love their CSV systems.

Reviews / "Under Pressure" WWJ article 2009

« on: December 05, 2014, 09:58:33 AM »

There are several references by contractors in this Water Well Journal article from 2009. As I post this at the end of 2014 you should understand that many of the VFD's mentioned by these contractors have already been taken off the market due to problems. You should also understand that many of the VFD's systems the contractors said had not given them any problems have most likely failed since this article was written in 2009.
