Low or fluctuating pressure? We test every point in your system and identify the exact cause before any repair.
When did your shower in San Rafael stop feeling like a shower? Was it gradual, or sudden? Both have causes. Both are fixable. And both are usually cheaper to deal with than people think.
Most water pressure problems are mechanical and localized. The hard part isn't the repair — it's figuring out which part is causing the problem. That's what we specialize in at Koda Plumbing Service Co.
We test pressure at the meter, main, and multiple fixtures to locate exactly where the loss is happening.
We test first, then replace only when confirmed. A common fix for low or high pressure.
We work backward from the showerhead to find restrictions in valves or supply lines.
Aerators, angle stops, cartridges, or supply line issues — diagnosed in logical order.
We treat sudden drops as urgent — burst pipe, failed pressure tank, closed main shutoff, or municipal issue.
Usually caused by failing pressure tank, degrading PRV, or hidden heavy usage/leaks.
