Do not put a metal Well X Trol in a confined humid place. Will rust.

Another thing to consider is my pump is 3/4 HP,
10 GPM.

That tank is bare minimum and I have a hard even calling it that.
I would look at the WX250 as a lot better fit for your pump. But there are other factors other than just the hp and rated gpm of the liquid end of the pump.

Wow!

You have a well on a ship?!

Now that's what I call a deep draft vessel.

Used in a Chilled Water AC System.

They're also used on yachts (and ships) for the fresh water system. As the system uses a pump to pressurize the water system and pump the water from the water tank throughout the boat/yacht/ship to all of the faucets, showers, heads, etc.

I got to thinking about GPM's so I placed a 5 gallon bucket in my bathtub and filled the bucket. It took 80 seconds (3.75 GPM). Drawdown at 40/60 takes 106 seconds (6.625 Gallons). Rated drawdown at 40/60 for my Water Worker HT-32B is 8.57 gallons.

I removed my well cap and I do have a leak at the swivel elbow that transitions my well line from vertical to horizontal. Is it leaking 1.945 gallons at the elbow? No, the leak is not that bad. Is the leaking diaphram affecting the drawdown? I don't know...probably.

The bath tub faucet is not a good source for determining how much water you pump is producing when running.

Also look up a pump curve for your model and make of pump. On a pump curve is gpm and the other side is TDH. Which is Total Dynamic Head. We is a calculation for vertical distance and pressure.

If you switch is set at on at 40 and off at 60 psi. Watch your pressure gauge when the pump is running. Try to turn on enough water sources to that the pump will run and stay at 50 psi. Using your 5 gal. buckets time how much water you are pumping at 50 psi for 1 minute. That will tell you what your accurate gpm is at 50 psi.

To convert your psi to tdh multiply 50 psi x 2.31 which equals 115.5 ft of head. The other reason for doing this it will tell you the dynamic pumping level in the well with the pump running.

Lets say that at 50 psi you determine that you are pumping 12 gpm. Look at the pump curve. Find 12 gpm. Then go across to the Total dypmanic head side of the chart. Lets say it say's your pump at 12 gpm is at 240 TDH. If you subtract the 115.5 head conversion for 50 psi that leaves a difference of 125' of tdh.
That would mean your dymanic pumping level in your well is 125'. That means that when your pump is running and pumping 12 gpm at 50 psi the water in your well stabilizes and stays at 125'.
The static water level which is not really an important factor is where it is with no pumping going on.

There one other calculation but in a system your size is not significant it is a friction loss calculation for pressure drop through piping, fittings and valving.

Hope that helps.


And any leak in your system should be fixed. When no water is being used you can think of your pressure tank and piping system to every valve and fitting in the system as being an inflated balloon. As you flush a toilet or open a faucet that balloon let out water (vs air) as water is being used the balloon is loosing pressure. Once the pressure drops to 40 psi the pump comes on to re-inflate the system. If irrigating a lawn for extended periods of time. You want to use enough water so that the pump will not reach 60 psi and shut off during that extended use of water or you will be short cycling the pump. Fix the leak as it is needlessly cycling your pump and doing damage to both the pump and tank.

I have one under the house, installed in 2002 or 2003,

no issues, no drama, still works fine

I just had a Well-X-Trol WX 250 (44 gal) installed a few weeks ago.

replaced 25 year old well tank that was 25 gal capacity

It came w pressure switch attached

My system is 40/60

Sdy, As I mentioned a few post above in my recommendation

Sounds like you had someone that knows what they were doing.
