Yes, pumping into a pressure tank makes a big difference. A 10 GPM pump can do about 20 GPM if there is zero head on it like yours. But it is not good for the pump. Above about 16 GPM the pump will upthrust and wear out the top of the impellers. It needs some restriction to keep it less than...

If you have a cistern or a well, a submersible is very quiet.

A VFD itself creates noise. But the real problem with a VFD is that it is like a Tar Baby you keep paying to replace and can't get rid of. VFD's are built with planned obsolescence as the main objective. They are made to make money for the manufacture, which ends up costing the end user many...

Probably have to make your own manifold with a hand full of brass tees and nipples.

You will lose about 5 PSI on the 15' of elevation. But 900' horizontal is no problem as long as the pipe is large enough. If the barn only uses 5 GPM or so, 1" pipe would work, but larger is always better.

I don't know how it has been working with two pressure switches. It would be hard to keep from having a cross connection when using power from two different places, plus it is not safe. Only one pressure tank is needed, even for multiple homes. The only check valve needed is the one down on...

Remove the pumptec and try it with a standard control box.

Like everything else, pressure tanks are destroyed from the pump cycling on and off. Any size tank will last longer when using a CSV, but as was said, you won't need nearly as large a tank.

As was said, low pressure switches are a nuisance. Either you are opening too many faucets, or the overload in the motor is tripping.

200' of control cable from a transducer can be a problem. Even with shielded cable there will be line noise. Most people switch to a CSV system after the VFD fails. That is what has kept us in business for 30 something years so far. Just don't replace it 3 or 4 times before you make the...

Sorry for your problem and sorry you got talked into a VFD. I have the patent on the in well pressure tank and Cycle Stop Valve and I quit using VFD controls in 1993, so I know how those work. The in well pressure tank doesn't hold enough water to work as a tank should or supply a house...

The smallest well pump you can get is 1/2HP. It will draw full 1/2HP load when running at max flow and allowed to cycle on and off as needed to fill the cistern. The cycling is not good for the pump. But it will be running at its best efficiency or it will be off. When restricting the flow...

All pumps are oversized. You have to install a pump that can handle peak demands, but the majority of the time the system is using a fraction of that amount. You also set the pump at 300'-400' because you don't know how far the water level will draw down when using peak demands. But when...

Higher flow is usually better for developing a well like Reach says. But it is hard to develop a well when the pump is cycling, at any flow rate. While you are using a 4 GPM faucet, the pump is pumping 12 GPM for 3.5 minutes, then 0 GPM for 5 minutes. This is causing the well to be surged up...

Sorry, been away. In our area a 3' seal is not enough. We are required to seal 20'-25' at the top. Below that we fill the well with gravel that looks like sand. But if your well is what is called a "rock" well, gravel pack is not needed. But they usually only case about the top 25' of a...

You have a pump that wants to put out about 3 faucets worth of water. Using anything less than 3 faucets wide open will cause the pump to cycle on/off no matter how large the pressure tank. A larger tank just slows the cycling down. But there are 1440 minutes in a day, so a cycle every 4...

An efficient pump is all you can do. There is no magic way to save energy. It takes X amount of KW to pump Y amount of water from Z a certain depth. It takes a lot of solar to do any irrigating. An elevated tank to store pressure doesn't save anything either. I would use a cistern storage...

Looks like a slide type pitless. I would just give it a pull.

Submersibles are my favorite. Check to see if it is allowed in your area. Grundfos pumps hold up well in salt water.

The pumptec looks for a 25% drop in amps and shuts the pump down thinking it is running dry. Restricting some pumps to 3 GPM can make the amps drop by 50% or so and the pumptec will not work. The Pentair pumps are not good at dropping in amps when the flow is reduced. They usually only drop...
