Yes, Simple Pump can efficiently fill residential pressure tanks. The pump is engineered to develop up to 45 psi pressure, suitable for most home pressure tank systems.

How Pressure Generation Works

Simple Pump generates pressure through:

  • Precision-machined components - Tight tolerances minimize leakage
  • Quality seals - 90 durometer urethane/buna seals
  • Leverage advantage - Lever arm multiplies your effort
  • Positive displacement - Each stroke moves a fixed volume

Pressure Capability by Cylinder

CylinderPressure CapabilityNotes
100CAUp to 45 psiBest for deeper wells
125CAUp to 45 psiModerate depth
200CAUp to 45 psiShallow wells, higher volume

What This Means for Your Home

A standard residential pressure tank typically operates at:

  • 30-50 psi range - Common household setting
  • Cut-in at 30 psi - Pump starts
  • Cut-off at 50 psi - Pump stops

Simple Pump at 45 psi can:

  • Fill your pressure tank to normal operating pressure
  • Maintain household water pressure
  • Supply fixtures and appliances

Factors Affecting Pressure

Your actual pressure capability depends on:

  • Static water level - Deeper water = more effort needed
  • Total lift - Depth to water plus pressure head
  • Cylinder model - Smaller cylinders = less effort, more strokes
  • Physical effort - Your pumping strength

Installation for Pressure Tank Use

To pump into your pressure tank:

  1. Check valve required - Prevents backflow
  2. Proper plumbing connection - Tie into pressure system
  3. Gauge for monitoring - Watch tank pressure

Realistic Expectations

With hand pumping:

  • Filling takes time - Expect 15-30 minutes for a full tank
  • Good exercise - Pumping against pressure is a workout
  • Effective backup - Provides water when power is out

Motorized for Easier Pressure Tank Filling

For regular pressure tank use, consider our Motorized Well Pump:

  • Automatic operation
  • Hands-free filling
  • Solar or AC powered
