Low Water Pressure Hot Water Greater Vancouver

When hot water pressure is lower than cold pressure in a Greater Vancouver home, the restriction is on the hot water side — and the cause is almost always at or inside the water heater.

What This Means

Cold and hot water typically have the same pressure at the outlet. If hot water pressure is noticeably lower, a restriction on the hot side is the issue. Common causes include a partially closed shutoff valve, a blocked dip tube, or a scale-restricted outlet connection.

Common Causes

• Partially closed shutoff valve on the hot water outlet
• Scale or debris blocking the hot water outlet fitting or the dielectric union
• Dip tube debris: a failed plastic dip tube can shed particles that clog aerators and fixtures
• Waterway scale in tankless units reducing internal flow capacity
• Backflow preventer stuck partially closed on the hot outlet (less common)

What Homeowners Can Check Safely

• Check that the shutoff valve on the hot water outlet at the tank is fully open
• Unscrew and check aerators on affected faucets — small particles from a disintegrating dip tube commonly clog aerators

When to Call a Licensed Technician

Water heater work involves gas lines, high-voltage wiring, and pressurized plumbing. Always call a licensed gas fitter or plumber for repairs beyond basic visual checks.

• Dip tube inspection and replacement
• Outlet fitting descaling or replacement
• Tankless waterway inspection and descaling if scale has reduced internal flow

Frequently Asked Questions

Why do I have good cold water pressure but low hot water pressure at every fixture?

When the pressure difference is present at every fixture simultaneously, the restriction is at the source — the water heater. The most common causes: (1) the hot water outlet valve is partially closed; (2) the dielectric union or outlet fitting is scale-restricted; (3) a failed dip tube has shed debris that partially blocked the outlet. Start with the outlet valve, then trace from there.

My aerators keep clogging with small white particles. Is that from my water heater?

White or off-white particles clogging aerators are often debris from a disintegrating plastic dip tube inside the water heater. Dip tubes are made of plastic and can crack and shed over time, particularly in units over 10 years old. The particles travel with the hot water and catch in aerator screens. Dip tube replacement resolves the source; cleaning all aerators resolves the symptom.
