Water Well 101......A few questions from a water well newbie

[Richard]

Though I don't have one, I like the idea of a larger tank.

We lose our power (it sometimes seems 2-4 times/week but that might be exaggerated)

Anyway, when we lose power, we have to be very careful about simple things like flushes..... I've got 4 toilets in the house so I figure I've got 4 flushes and those will probably drain most or all of my tank.

If we see a really nasty storm on the horizon, I'll go ahead and fill a couple of pitchers of water so we'll have something saved up.

Larger tank would fix a lot of that for us.

None. Probably meant a 220 volt pump. No residence is 3 phase

Nope, they make inverter VFD controllers that make 3 phase out of 220V single phase.

This is true... had to do it in Pittsburgh last year, something to do with back feeding a neutral I think???

With a rotary phase converter you feed it from both sides of a single phase 240V line and play with capacitors to get the voltage right.

As a local 'go to' handyman type I've maintained many pump systems.
A 16-20 gal bladder type tank is all U need to have constant pressure.
Naturally the control switch must be properly set.

Mine is a 40/60 control on a 16(?) gal bladder tank and believe U me I have all the pressure I ever want, heck when taking a shower if my wife does a wash load I don't even know it.

I am quite certain that you do have plenty of pressure if you have your pressure switch set correctly.
The problem with a small (16 gal.?) tank though, is pump cycling.
Your pump may be cycling on, when you draw only a gallon or two of water.
Pump cycling = pump wear.
A larger tank requires fewer pump cycles between water draws.

If you have a frost free yard hydrant or 2 or 3 that are located in between the well pump and your pressure tank piping,

"do not install a check valve just before the pressure tank"

because your yard hydrant will only work when the well is turned on.

Also have water in containers for emergency use for when the well goes out and the pump guys can't get there for a few days. Also for when the power goes out unless you have a way for the generator to run the well pump.

This is very important for maintaining ANY household.

I'd strongly recommend either a few "rain barrels" or a "tote". This provides a buffer for when the water fails and getting it fixed.
I've a 275 gallon tote strategically placed under roof runoff. Set it up to provide water for rinsing stuff around the yard. A few times the municipal water has stopped. We found it easy to use bottled water for CONSUMPTION but the tote made a big difference in flushing.

We have a 8000+ wattage portable electric start generator specifically to run the well pump, refrigerator, and freezer, when ever the power goes out.

All I have to do is roll it to the back deck, plug it in, start it, and go inside to flip the switch in the transfer switch panel box.

And also the plus is, having some lights, TV, internet, and microwave...

"3 phase pumps"?
How many private residences have 3 phase power?

I think what he is referring to is a variable frequency drive pump. Not three phase. It cycles up and down according to demand.

Same here. Repairs after 40 years are next to nothing. 300 feet of plastic piping, and 300 feet of underground cable continue to work without issue; same for the bladder tank and pressure switch. At 40/60 there is no issue with water pressure; We can shower, wash clothes, and run the dishwasher simultaneously without issue.
If a water pump is going to go, like they do every 15 or so years, be assured it will happen at the worst possible time like Friday the 3rd of July guaranteeing you can't buy a quality replacement for a few days. After that happened to me I now keep a fully plumbed backup on hand. What was nice about that was I could really shop hard to find another Goulds at a great internet price; and that "insurance" has thankfully not been needed.

No, they are 3 phase VFD capable pumps. The controller makes 3 phase out of single phase and uses the VFD to vary the pump RPM to keep a constant pressure on the output of the pump.

Here is the Grundfoss site for their single to 3 phase controller line: Grundfos CU331SP Variable Frequency Drive | Grundfos
