If you’ve noticed brown or discolored water coming from your faucets or experienced odd-tasting tap water, don’t even read the rest of this blurb, call Southern New Hampshire Plumbing, Heating, Cooling, because you most have a backflow problem.

Backflow occurs when there is a water pressure change in your piping which causes either back pressure, making water flow in more than one direction, or back siphonage, when the pressure from the water supply source becomes less than the pressure in the plumbing. In any event, backflow can result in waste water contaminating the fresh water you use to drink, bathe and clean, and can be extremely hazardous to your health.

Luckily, the professionals at Southern New Hampshire Plumbing, Heating, Cooling are available 24/7/365 to resolve your backflow emergency. From simple solutions such as creating an air gap or a barometric loop, to more advanced solutions such as a reverse pressure principle backflow preventer, we have the knowledge to diagnose your problem, properly identify the cause, and create a long term solution that will protect your plumbing system from backflow and protect you from contamination backing up into your water supply.
