Plumbing Tips

  • Water Pump

    Always select the smallest pump that will get the job done. This saves power and operating cost. Pump cutoff pressure must always be less than maximum shutoff pressure. When pressure goes up, capacity goes down. Adequate discharge capacity is 1 gpm (gallons per minute) for every fixture in your home. This includes the faucet, shower and water closet.

  • Pressure Pump

    To ensure adequate pressure throughout the home, make sure there's enough discharge pressure at the highest outlet in your home. If maximum shut off pressure exceeds 100 psi (pressure per square inch), a relief valve is required.
