Water System Problems We Solve
Pressure issues, pipe failures, water quality problems — diagnosed and fixed right across St. Thomas and London, Ontario
Low Water Pressure
Whole-home pressure problems traced to the source — failing PRV, corroded main line, closed valves, or municipal supply issues.
Discoloured or Rusty Water
Brown, yellow, or rust-coloured water signals corroding galvanized pipes or sediment buildup that need immediate attention.
Leaking Supply Lines
Interior supply lines — under sinks, behind appliances, in walls — repaired or replaced before small leaks become water damage.
Main Water Line Issues
Wet yard patches, sudden pressure drops, or unexplained high bills point to a failing or leaking main service line.
Hard Water & Scale Buildup
SW Ontario's hard water causes scale in pipes, fixtures, and appliances — reducing efficiency and lifespan over time.
Backflow Contamination Risk
Unprotected irrigation systems and hose bibs can allow contaminants to enter the clean water supply.
Common Signs You Need Us
Water system issues get worse over time — and small leaks or aging pipes don't fix themselves. Spot these early and save.
Water pressure noticeably lower throughout the home
Hot water has a rust, orange, or metallic tint
Unexplained spike in monthly water bill
Wet or soggy patches in yard with no recent rain
Knocking, banging, or hissing sounds in walls
Water tastes metallic, earthy, or has an odd odour
Appliances scaling up or clogging faster than usual
Shut-off valves are stiff, seized, or won't close
Supply lines are original to a home 20+ years old
Visible corrosion, green staining, or wet spots on pipes
Noticed any of these? An assessment takes an hour and tells you exactly where you stand.
