Irrigation / Re: Choosing CSV and System Configuration
« on: August 30, 2021, 12:29:36 PM »
Sorry. Can't use those ports for anything. Not big enough for tank and won't have the right pressure for a switch or even a gauge.

The CSV part of the PK1AM needs to go before the hydrant.

The CSV always functions well. it is the hydrant that won't function well if installed prior to the CSV. All that means is the CSV must be installed prior to the pressure tank/switch and before any hydrants or tees in the line. We make the PK1AM or the PK125 to take care of that.

Applications / Air Release Valve for Deep Set Turbine without foot valve
« on: August 11, 2021, 11:48:03 AM »
Here are some pictures of a CSV system installed 15+ years ago for a deep set turbine pump. There is no foot valve on the pump, as is usual with many line shaft turbines. When working on a pressurized system using a pressure switch, getting rid of the air in the column pipe is a necessity. On this system the static water level is more than 100' deep and 100' of air in column pipe must be dispelled when the pump starts. Using a 4" normally open valve on a tee prior to the Cycle Stop Valve lets the air escape as fast as needed. This valve is designed to start closing as soon as water enters the pilot control valve. A needle valve adjust the closing speed of the valve as needed. This facilitates a smooth change from air to water in the system. As the air release valve closes it increases back pressure until the silent check valve installed prior to the Cycle Stop Valve slowly starts to push open. Once the air release valve is closed the Cycle Stop Valve is in control until the pump is shut off to due to no demand.

Applications / Re: Recommended Pump / CSV / etc. for New House
« on: August 07, 2021, 08:18:41 AM »
Well I have the granddaughter this weekend. Don't have time to reply to everyone at TL until Monday. At that depth the 15 GPM pump would better than the 12. Myers makes good pumps in the all Stainless Steel ones with the straps down the side, as they are a copy of the Grundfos. But the plastic impeller version like the one yo posted have "thrust pads", which means it is a floating stage type pump that I do not like. Thrust pads and floating stage pumps are designed to wear out more predictably than floating stack type pumps.
The 1HP, 33 GPM pump will not pump the well dry because when using a Cycle Stop Valve it is not a 33 GPM pump. The CSV sizes the pump to match the amount you are using. So if you never use more than 10 GPM, the CSV never lets it pump more than 10 GPM. it is just a cheap pump, that is as good as the floating stage Myers if not better.

The PK1A with a 10 gallon tank and a 50/70 pressure switch will work fine for that system. I don't see a 15 GPM series Myers? But the 12 GPM, 3/4HP would work. You might also consider the 1HP, 33 GPM, Hallmark because of the price of 150 bucks. It will build as much pressure as you need and even though it is a 33 GPM pump the CSV will make it into any size you need down to 1 GPM.
230 volt is best. 2 wire is fine. 3 wire is ok as well but needs a control box.

Yes, 40 to 60 and a constant 50 while using water is all you will see after the CSV.

« on: June 23, 2021, 08:09:59 AM »
Sorry for the delay. I don't know of any 12 volt pumps that will work. You will need a jet pump, which will be 115V or 240V and needs to be powered by an inverter to work with solar.

Still need a vent as it is not good for a well to be under vacuum.

I am not familiar with that Shur flo pump? If it is a positive displacement type pump, as most RV style pumps are, it will not like having its flow restricted with a valve. Can you get me more info or a curve for that pump?

The well cap needs a screened vent. Not good for a well to be under vacuum.

Valve Tech / Re: gpm and sprinklers
« on: June 15, 2021, 03:44:06 PM »
It knows because when you shut off the sprinklers the pressure increases above the setting of the CSV. it then closes down to 1 gpm which has no place left to go except the tank.

No! The CSV only sends 1 gpm to the tank AFTER you turn off all sprinklers and faucets.
