Backflow Services

backflow services

We all rely on having clean water. It’s absolutely essential to living a healthy life. Keep your drinking water safe from possible contaminants with backflow services from Hill Plumbing and Air. Our licensed plumbers are well-versed in the installation, repair and inspection of backflow systems.


A backflow preventer is a cross connection device used to protect water supplies from contamination. You may not know it, but water supply systems, irrigation lines and fire suppressant lines are required to have a backflow preventer. These devices are commonly used on both commercial and residential water systems. Furthermore, the DHEC requires backflow systems to be tested once a year. Routine backflow preventer testing is absolutely crucial to protect drinking water from becoming contaminated.


Hill Plumbing and Air employs a dedicated crew to serve residents and businesses in and around Sumter, Manning, Santee, Camden and Florence to address all issues regarding backflow preventers. Our technicians can perform annual re-certifications, new installs, and any repairs that might be necessary. ​Our backflow services include:

  • Testing
  • Repair
  • Installation
  • Inspections

Having a faulty backflow preventer is extremely dangerous to your home and your family’s health. If a broken backflow goes unnoticed, contaminants can slowly enter your water and cause serious health issues. Make sure to protect your home’s water with backflow services from Hill Plumbing and Air. Contact our team today to schedule an appointment for any of our professional backflow services.
