I RECENTLY PURCHASED A 2 ACRE PARCEL IN NORTHERN WASHINGTON STATE. PRIOR TO BUYING I DID MY DUE DILIGENCE AND TESTED SEPTIC AND WATER...THE WELL IS A SHALLOW WELL THAT PRODUCES 4GPM WITH A 12FT STATIC LEVEL WITH 1 FT DRAWDOWN AFTER 1 HOUR.....IT HAS A BUNCH OF JIMMY RIGGED WIRING (EXTENSION CORD) A LEAKY CRAFTSMAN 3/4 HORSE JET PUMP (SMALL DRIPS occasionally) A 37 GALLON PRESSURE TANK AND THATS IT IM CURRENTLY HOOKED UP TO THE SOLE HOSE BIB WITH A GARDEN HOSE LIVING IN A TRAVEL TRAILER ON THE PROPERTY ......(THE WATER PRESSURE IN MY TAVEL TRAILER IS GOOD FOR SHOWERS BUT WHEN SINKS TURNED ON IT ROBS ALL THE PRESSURE...IM CLOSE TO FINISHED ON MY 2300 3 BEDROOM 3 BATH HOME AND JUST LAID THE 1 INCH POLY UNDER GROUND AND AM RUNNING A HEATER AND NEW POWER TO WELL HOUSE FOR PROPER SUPPLY. MY PLAN IS TO DIY A NEW PUMP PRESSURE TANK ( NEWER AND BIGGER IM THINKING) AND LOOKING INTO THESE WATERWORKS DIGITAL PRESSURE CONTROL SWITCH SO I CAN MIMIC CITY WATER OR ATLEAST HAVE GOOD PRESSURE.....IM ATTEMPTING NOT TO REBUILD ENTIRE PUMP HOUSE HOWEVER IF I HAVE TO I WILL.....WHAT DO I NEED STORAGE TANK? WILL BIGGER PRESSURE TANK AND NEW PUMP WORK I SEE A KINK IN THE HOSE OF TANK COULD THAT ATTRIBUTE TO IT WHATS THE BEST RECOMMENDATION ALL HELP APPRECIATED.....NEW BUILD HAS LOTS OF SHOWER IN MASTER NOT TO MENTOON I HAVE A HOUSEHOLD OF 6 NEW BUILD IS ABOUT 80 FEET AWAY FROM WELL

WHY ARE YOU SHOUTING AT US? Lol!

With two pipes going down the well that is a Deep Well Jet Pump. You didn't say, but looks like 5"-6" well casing. If that is the case a submersible would be a much better option. I don't think 4 GPM is enough to do what you are wanting. But with the static at 12', if the well is deep enough, you may have enough storage in the well to not be limited to the 4 GPM for short periods. If not, a cistern storage tank is the best option.

No matter how you pump it, submersible or jet pump, cistern or not, the standard pressure tank/pressure switch controls like you have now is not far from the best way to go. You don't need a larger pressure tank or any fancy electronic controls. All you need to do is add a Cycle Stop Valve to get the constant pressure that makes your water system reliable and stronger than any city water supply.

If you know the depth and diameter of the well it will help you decide between submersible or jet, and cistern or not. But here are some drawings of how to easily DIY a set up with the well as the only source of water and/or using the well to fill a cistern. There are lots of different options available. The PK1A kit is all you need to control either type pump in the well or in the cistern.

thank u brother this helps immensely so i'd assume the best first step is to run a weight and fishing line down casing to measure full depth of the c well??

 

[Valveman]

I assume there is a tail pipe on the bottom of the ejector. Either way you will have to pull the pipes to be able to run a weight on a string to the bottom. (Don't lose the weight and string. Lol!) For every foot of water above the setting of the pump you have about 1.5 gallons stored. If you can set the pump at say 60' or deeper, you won't need a cistern.

spoke with a local guy he suggest putting a 80bsomething size pressure tank with a new submersible pump in my question is if i put say a 1 hp submersible pump rated for say 10gpm and my well is a 4 gpm well what will stop it from sucking to much water out of the well do i need a smaller submersible or is there either no risk or a certain way to mitigate its draw?

If the well only provides 4 gpm then I would use a 1/2 hp pump, they will pump 10 gpm, depending on the head.

Stupid question, what do the 2 pipes on the pump do? How do those pumps work?

 

[RS]

It appears to be a 2-line jet system, for when the water table drops below 25 feet. the smaller line is water going down through a venturi that forces water up the larger line. If the casing is large enough your better off with a submersible pump.

A 1HP, 10 GPM pump would be correct for a well with the pump set at about 300' deep. There is no way your two pipe jet pump ejector is set deeper than 100'. A 3/4HP, 10 GPM pump will work if the pump is set at about 200'. A 1/2HP, 10 GPM pump is probably all you need as it will work with a water level down less than 100' deep. If it is less than 50' setting you need a cistern.

The 80 gallon tank only holds 20 gallons of water, but that is a lot for a 10 GPM pump. I would have recommended the same tank 30+ years ago. But the pressure tanks only purpose is to limit the on/off cycles of the pump, and when you have a Cycle Stop Valve to do that for you, you don't need a very large tank. The CSV and a 4.5 gallon size tank will do a better job and deliver much stronger constant pressure to the showers.

You need about a 10 GPM pump to handle peak demands. There will be 4 GPM coming into the well while you are drawing out 10 GPM. So, if the well has 50' or 75 gallons of water stored in the well, the pump can produce 10 GPM for 12.5 minutes. That is usually enough to handle peak demands without needing a cistern. If the pump runs at 10 GPM for longer than 12.5 minutes it will pump the well dry. Then you need something like the Cycle Sensor to shut the pump down, time out, then restart the pump.
