I'm still confused how you can have the water go in series from one tank to the other with only one fitting on each tank.
Spiker, I understand why they want the filter downstream from the tank. It allows sediment to settle to the bottom of the tank and gives longer filter life. I would rather backflush the filter than drain the pressure tanks monthly. Have you heard of any downfalls to having the filter upstream of the tanks, provided that the pressure switch is upstream of the filter?

As sediment collects in the filter it will make the pump work harder or blow a seal, thus it could shorten the life of the pump if the filter is before the tank. And if you put it there and after the pressure switch and before the tank you could end up short cycling the pump. So yes, you can put it there and it will work , but no good Plumber is going to do it or would a manufacture stand behind there product .

The only thing I will install between the pump and a pressure tank is a check valve.

When you come out of a tank you use a tank tee. That fitting has two outlets that allow you to use 1 inch or 3/4 inch fittings, that is how you would series two tanks together.

What is hardest on a motor is the starting cycle , so a bigger tank or two tanks will cut down on the cycles and that will help extend the life of the pump.

What is the reasoning behind this??

The check valve holds the water from returning to the well and relieves the starting pressure on the pump. I started a discussion about this subject last year. I finally resolved my problem of sand in the water heater by installing a sediment filter after the tank before it goes into any plumbing. This is an expensive filter, but requires very little maintenance. Just empty the canister monthly by using the valve at the bottom of the canister and draining water into a milk jug. The filter costs about $300. If you want to put a secondary filter on the line, then be prepared to do filter changes. The larger the filter, the better they work. I suggest that you have a water sample tested first and then decide what type of water treatment you need before doing anything. Just remember that the sediment that comes from the well will clog any appliance that you have in the house, such as the water heater, water softener, etc. That is the reason to have the sediment filter right after the tank. If you have an existing home and don't know if there is a sediment problem, look in the toilet tanks. If you find sand in the bottom of the toilet tank, they you have a problem. I didn't think about this until my water heater started to bang every time the burner came on. The heater manufacturer clued me into what was the cause. The only bad part is that once it is in the tank, there is no way to remove it. I was draining water from the water heater tank on a regular basis, but the drain doesn't come off the bottom, but a couple of inches above the bottom. That is why the sediment never came out.

You install a check valve on the inlet side of the expansion tank to maintain the pressure on the system. That way your not relying only on the check valve down in the well, on the pump, to maintain your system pressure.

Most check or foot valves used in domestic water systems have a soft seated check with a spring to hold them closed. They can and due fail, or debris can get caught under the check. If you have a second check at the tank and one of the checks fails, your system will still work fine.

Also if you have only one check or foot valve and it fails, you could create a backflow situation that could drain the entire house , pressure tank and maybe even the hot water heater ,toilet tanks or any other cross connection back into the well.

People will buy the fluid master 200 instead of the 400 to replace a toilet fill valve to save a buck.

((( The 400 has a check valve built in the 200 doesn't. )))

You will find even on new homes, on a Municipal water system, that there is a double check valve just before the water meter where the water enters the house to prevent backflows.

If it is a shallow well with a foot valve for the check , you put a second check on the inlet of the pump and not on the tank. Some jet pumps even come with the check build right into them.
I will also install a tee with a plug before the check to make it easyer to prime the jet pump system.

That's the reason for the second check valve at the tank.

"Well Hardware" seems like the right thread to ask my question...

I discovered the original well right where I should have expected it, next to the water tower and straight below the windmill's plunger connection.

I need a new cover to shield the open well pipe. It measures about 5.75" ID. Is there some sort of standard plug or cap intended for this purpose? Where would I order it?

Thanks for any advice!

Thank you.

To sort out some questions that haven't really been made clear.

Two tanks:

Series: Input to tank one, oulet of tank one to input of tank two, outlet of tank two to house system.

Parallel: Pump to T - one leg to tank one, one leg to tank two.

As for operation. It really makes no difference at all altho in series any sediment will have a tendency to settle in tank one.

Reason for putting filter after the tank: The filter causes a restriction in the flow. You do not want the pump working against that. It adds wear and tear to the pump.

dbelisle,

Thanks for the professional input. It makes sense.



turnkey,

I like the way you explain things, simple and straight forward.

I will second the thanks!!! Nice to get good info from you all. I will install my filter after the pressure tank and advised.
