I just can't picture the water flowing in opposite directions through that 1.25" pipe. Maybe the water from the pump is flowing to whatever is using the water at the same time it is filling the tank. The pressure would keep the water flowing from the sink while excess went to the tank. Yes, that sounds like a solution.

Water flows from higher pressure to lower pressure. Pressure from the well is probably 80# or more. Standard tank pressure is probably 75#. (And no, them ain't hashtags.) The shut-of/on switch is probably set to remain off in the 75# - 50# range, and then start the pump when pressure in the system drops below 50#. While the pump is running, and you turn on a faucet somewhere water will flow to both lower pressure destinations.

You could always add "T's" and new line. But if it works for the current dime, think hard before changing it... I want to put a "On Demand Hot Water Tank" in my home. But from what I have heard it needs another pipe to cycle the hot water.

What is so hard to understand? While you are drawing water the water may come from the tank or the pump or from both. When you turn the faucet off, the pump may run for another few seconds to build up pressure in the tank. The bladder in the tank has the compressed air on the top side and the water below. Simple as that.

Think! Is there a T in the inlet/outlet line.

Not wanting to get into any discussions re water flowing both directions at the same time but you haven't forgotten that both the dishwasher and the washing machine have a system whereby they won't start until the water has filled to the correct level ? So if the well pump is busy pushing water into the tank the two appliances will just stop and continue filling once the water can flow the other way again.

Jerry, you must know three important things to be a plumber.

1. Do not look into the end of an open drain pipe.
2. Do not lick your fingers.
3. Friday is payday!😁

By the way, being a union plumber is a very lucrative way to earn a living with great benefits and retirement. Our lives would be quite shitty without plumbers and the health and safety of sanitation depends on them.

The way I work, no one would want to hire me as a plumber. I take my time, and I take breaks. I also take trips into town for parts. When I'm done, the job is fine, and all is well with the world. I have a list of other projects, but there's no rush.

I hope you put a Tee-fitting on pipe that goes to the pressure tank so water can go either to the tank or the house piping.

I also have a check value near the pump head in the well. Otherwise, once the pump shuts off, the water drains back down the pipe and strange things also occur. The vacuum created can only support a ~30 foot column of water. No way to use an old hand pump to pull water from even a 50 foot deep well.

The pump on that ol' hand pump was way down the well. It was pushing water, not pulling it!

That happened years ago after a well pump was replaced. The plumber didn't include a check valve. Another time, there was a leak in the well pipe (200' down), and he had to come pack and pull it up and repair it.
