Water Pressure Problems in Oshawa

Water pressure problems come in two flavours. Low pressure makes showers weak and appliances slow. High pressure can feel great but strains fittings, appliances and water heaters. Figuring out whether the issue is one fixture, one floor, the whole house or the whole street is the first step.

Weak flow at one fixture only
Pressure drops when two fixtures run at once
Banging pipes or leaking relief valves (high pressure)

Common causes

Failed pressure-reducing valve
