Deduct Meters


Backflow Installation & Testing

Residential & Commercial

Call for Prices

All properties with lawn irrigation systems and all commercial and industrial buildings require backflow devices per plumbing code. The lack of a properly working device at your property could impact the health of your family or neighbors by contaminating the water supply with chemicals from your lawn.

Some Water Departments test your backflow once a year. Failed backflows must be repaired and the water department can turn your water off to protect the city’s water supply.

Our Licensed Team can test and or make any repairs and get your system up and running

Manchester NH Sewer Rate
$3.73 per 100 cubic feet of water

1 cubic foot = 7.4805 gallons

100 cubic feet of water = 748 gallons

$3.73 per 748 gallons or $.005 per gallon

5-6 heads per zone = 5 GPM Average

Formula: 5 GPM x minutes x the number of zones x 30 days = Gallons per month / 784 = ?

? X $3.73 = sewer cost per month

Example #1
per month
  • 6 Zones Watering
  • 30 minutes each zone
  • 5 GPM x 30 minutes = 150 gallons
  • 150 gallons x 6 zones = 900 gallons per day
  • 900 gallons x 30 days = 27,000 gallons per month
  • 27,000 / 784 = 36.10
  • 36.10 x $3.73 = $134.65
  • Cost per month $134.65
