Pump Installation · Riverdale, CA

The right submersible pump, set at the right depth

Well pump installation and replacement covers the pump side of a water well. We choose the submersible well pump that fits your well and your household, then set it at the right depth. Big River Drilling sets pumps in the wells it drills and replaces worn ones across Fresno, Kings and Tulare counties.

When the pump quits for good or keeps failing, it is time for a new one. If the old pump might still be saved, start with well pump repair. We are based in Riverdale, and we take well and pump calls 24 hours a day, seven days a week. Call or text (559) 867-3806 for a free estimate.

What We Handle

  • Submersible well pumps sized to your well's yield and your household's peak demand
  • Well pump replacement in existing wells, with the old pump, pipe and wire pulled
  • Pumps set in the new wells we drill, sized from the pump test
  • Drop pipe and pump wire sized to the setting depth and the length of the run
  • Check valves spaced for the pump's depth, per industry guidance
  • A control box or a constant-pressure drive, matched to the motor
  • A watertight well cap sealing the casing around the pipe and wire
  • Installing the electrical to the pump as part of the well job

Which Submersible Well Pump Fits Your Well?

Sizing starts with two numbers: what the well can give and what your house uses at its busiest. A Water Systems Council table puts the minimum pump at 7 gallons per minute for one bathroom, 14 for two. The council's general rule is to never install a pump with more capacity than the well. When the well gives less than the house needs at peak, a larger pressure tank can usually cover the gap.

For a given flow, horsepower follows the lift. The pump lifts water from the pumping level to the tank, then builds pressure on top of that. Each pound of pressure counts as about 2.31 feet of extra lift. A deeper water level or a long uphill run takes a stronger pump.

A regular submersible runs at one speed. A three-wire pump starts from a control box, while a two-wire pump keeps its starting parts in the motor. A constant-pressure drive instead speeds the motor up or down to match your use. Pressure holds steady, and the motor ramps up slowly instead of starting at full power.

Well Pump Installation, From Drop Pipe to Well Cap

The pump hangs on drop pipe, with its wire strapped to the pipe on the way down. The wire is sized to the motor and the length of the run, from pump makers' cable tables. Too small a wire over a long run drops the voltage the motor needs.

When the pump shuts off, check valves keep the water in the pipe from running back down the well. That guards the pump against backspin and water hammer. Industry guidance puts one within 25 feet of a pump that has none built in. Deeper settings get another about every 200 feet.

At the top, a watertight well cap closes the gap around the pipe and wire, as California's well standards require. The same standards call for a way to measure the water level, such as a plug in the cap. Installing the electrical to the pump is part of our job. The power line runs in conduit through the trench to the well head.

Well Pump Replacement Around Riverdale

State well records show wells around Riverdale getting deeper. New domestic wells with a Riverdale address had a median depth of 245 feet from 1990 to 2009. Since 2020, the median is 500 feet. That can mean a deeper pump setting and more lift.

The annual report for the Kings Subbasin, which includes Riverdale, finds water levels dropping in normal and dry years. Pump sizing guidance calls for enough pressure for a lower water level later. So the setting and the horsepower should leave room for a dry year.

If the water has dropped toward the old setting, the new pump can go deeper. That works when the well has room below the pump. If the well itself is failing, the fix is a replacement well, not a new pump.

How We Work

How a Job With Big River Drilling Runs

From the first call to water at the tap, here is how it goes.

1

Call or Text for a Free Estimate

Call or text (559) 867-3806, or send the form. Tell us about the property and what you need, and we set up a free estimate.

2

Site Visit and Well Records

We look for a well spot with room for the rig. State standards keep it at least 100 feet from the septic tank and leach field. We also pull the records of nearby wells.

3

County Well Permit

As the licensed driller, we apply for the county well permit. Drilling starts only after the county issues it.

4

Drilling, Casing and Seal

Our mud rotary rig drills the hole. We set the casing and gravel pack, then place the sanitary seal that keeps surface water out.

5

Development and Pump Test

We develop the well to clear out drilling mud and fine sand. Then a pump test measures the flow and tells us where to set the pump.

6

Pump, Tank, Lines and Water On

We set the pump and the pressure tank and run the lines to the house. State standards call for disinfecting the well before the water goes on.

FAQ

Pump Installation Questions, Answered

Common questions about pump installation across Fresno, Kings and Tulare counties and out to Kern, Madera and Merced, about 60 to 70 miles around Riverdale. If yours is not here, call and ask.

Call (559) 867-3806

Is a constant-pressure drive better than a control box?
Not always; it depends on how you use water. A drive keeps pressure even when the shower and washer run at once, and it can use a small tank. A control box system is simpler and leans on a bigger tank to limit starts. The estimate lays out both.
Can the old drop pipe and wire be reused?
Sometimes, if they are in good shape and suit the new pump. Pulling the old pump brings up its pipe, wire, splice and check valves, so each one can be checked. Worn or corroded parts are replaced before the new pump goes down, and the price reflects what is reused.
Do you handle the well pump wiring?
Yes, the well pump wiring is part of the pump job. That means the wire down the well, the splice at the motor, the control and the pressure switch. Pump installation falls under California's C-57 well drilling classification, and Big River Drilling is a licensed C-57 well drilling contractor.
Should the pressure tank be replaced with the pump?
Only if the tank is failing or too small for the new pump. A pressure tank's job is to keep the pump from starting and stopping too often. Tank size is matched to the pump's flow, per the Water Systems Council. The estimate says whether your tank can stay.
How much does well pump replacement cost?
It depends on your well, so we price it after a free on-site estimate. The pump's horsepower and setting depth move it. The length of pipe and wire, the control box or drive and any tank work count too. For market numbers, see what pump replacement costs in California.
Does a well need disinfecting after pump work?
Yes. California's well standards call for disinfecting a domestic well after work on the pump, before it goes back into service. A few days later, a state-certified lab can test the water for bacteria. We can point you to one.

Helped out my parents asap when the others wanted us to wait 2 weeks. He came out same day!!!! and changed the valve in only 10 minutes “thank you sir!! “ (water well drilling)

Open 24 hours. The owner is always available and always answers the phone or calls back. He’s very attentive, and when we have problems with the well, he will come out and check it immediately. He takes full responsibility for his work, which is excellent. we just call and he’ll walk us through the situation and it’s usually something simple. He also was able to get us a well at reduced rate through a program that he works with
