Galvanized pressure tank for well

Good Evening!

Last winter our well pump died. We got a plumber out who replaced the pump at a fairly reasonable rate, but I think there was a problem. He "upgraded" our well pump from the prior 1/2HP version to a 3/4HP model. I didn't know much about such things at the time, but I now think this is problematic as the pump only seems to come on for a short period of time when water is being used, maybe 10 seconds. I understand this cycling could rapidly kill the pump.

We have a galvanized pressure tank. It doesn't have a bladder, and this is important because we have an iron reducing filter right after it which requires exposure of water to air in the tank to work. One plumber thought the galvanized tank is original to the house (). Given its age and the possible short cycling issue, I'm wondering if I should consider replacing it with a larger tank.

Anyone have any insights or advice?

Thank you in advance!

There could be two issues:

1) A the galvanized / conventional tank allows water to be in direct contact with the air in the tank. Over time the air will dissolve into the water and is removed when you use the water. This results in low pressure in the tank. This low pressure will  cause short cycling. I believe the pressure in the tank should be ~2 PSI below the pressure the well pump turns on. If possible I would test the pressure tanks pressure and refill as the first step.

2) How quickly a well pump cycles depends on a few things; how big the tank is (the larger the less frequent), how high the water pressures is set (the higher the quicker as the air takes more space in the tank), and how much water is demanded ( pretty self apparent). If your tank is setup correctly and you are still short cycling a bigger tank may be needed, there are charts online you can reference.

(As a reference point, we have a low flow master shower, nebia 2.0, and only two people in the house and our well pump has cycled 42 times so far this MONTH).

As for the suggestion to replace the pump, I suppose it could be cost effective ... if you have a shallow well or a jet pump ... but a deeper well with a submerged pump, I don't know.

Edit: (well technically reviewing your post before I hit post): Are you worried about the well pump only running for 10 seconds at a time or are you worried that there are short periods between times when the well is running? My understanding of short cycling is that the well turns off and on frequently when there is a water demand; basically the concern is the number of starts and stops. So, if your larger pump fills your tank quickly, but then rests for an extended period of time before restarting you are probably fine.

All water storage tank owners must know that the key concept behind a professionally installed well system is pressure. As the water pump forces water upward from the well into the piping system of your house or office, pressure slowly builds up. So basically, the purpose of having a water pressure tank is to hold, regulate, and release this pressure as necessary.

In order to fully understand the importance of mounting a stainless-steel or galvanized pressure tank in your system, we&#;ve listed a few things that explain why it is actually a good investment.

1. It regulates system pressure consistently.

Groundwater that gets to the surface through a well system is naturally pressurized. However, the amount of pressure applied through the system might not constantly meet the demands of the whole household. The stainless-steel pressure tank stores water and maintains it under pressure, and discharges it on demand whenever a faucet or shower is used. Without adequate pressure, water supply from these fixtures would trickle out slowly. Your pressure tank will guarantee that the system pressure is within the appropriate range, delivering enough water pressure throughout the entire household.

2. It reduces abrasion on water pump.

Because the galvanized pressure tank is able to hold a certain amount of water under pressure which can be used on-demand, it eliminates the need for uninterrupted water pump usage. With a high-quality pressure tank, your pump will only be turned on when the system pressure plunges below the threshold level and will shut off again once the pressure reaches the limit.

Without a water pressure tank, your pump would be turned on every time a faucet or shower is used. This incessant usage would cause abrasion on the pump and would absolutely require more frequent maintenance and repair, or worse, replacement.

3. It reserves water supply storage.

In case of a power outage or pump failure, water can still be accessed if you have a pressure tank. The water stored in the tank will continue to be used until it is exhausted or until power is restored. A well system without a pressure tank will immediately cease to produce water as soon as the water pump shuts off.

4. It saves a great amount of energy.

With the intermittent use of the water pump due to the pressure tank reserve, electricity is used less frequently and therefore will lessen your energy costs. A well system without a water pressure tank would require consistent pump usage.
