General Plumbing Service in San Francisco, CA
The Everyday Repairs That Keep a Building Running
Most plumbing calls are not emergencies at all. They are the angle stop that will not close, the hose bibb dripping steadily into a light well, the disposal that jams every third week, and the pressure regulator quietly running far too high. None justifies its own service call, and together they wear a building down. Malcolm Plumbing & Mechanical handles that everyday work for homes, apartment buildings, and commercial tenants throughout San Francisco, CA and neighboring Peninsula cities.
Booking several small items into one visit costs less and interrupts less than calling three separate times across a month. While we are there, we check pressure, shutoffs, and visible piping and tell you plainly what is closest to failing next. Licensed and insured, free estimates, a one-year labor warranty, and 35+ years of local service. Send your list through our contact page and we will schedule a single visit that covers all of it.

Drain Cleaning and Maintenance
Kitchen, lavatory, tub, and floor drains all slow for different reasons, and the right approach depends on which. Cabling, augering, and jetting each suit particular situations, and choosing correctly matters more than the size of the machine involved.
Valve and Shutoff Replacement
Main shutoffs, branch valves, and fixture stops all seize with age, and a valve that will not close is worse than useless in an emergency. Replacing them while the system is calm costs a fraction of doing it under pressure.
Water Pressure Testing and Regulator Service
Excess pressure quietly destroys appliances, fixtures, and supply lines throughout a building. Measuring static and working pressure identifies whether a regulator is drifting, has failed entirely, or was never fitted where the incoming street pressure clearly demanded one.
Hose Bibb and Exterior Plumbing Repair
Outdoor taps take weather and physical abuse that indoor fixtures simply never see, and their leaks often go unnoticed for months. Rebuilding or replacing them, and adding proper vacuum breakers, stops both the waste and the cross-connection risk.
Repiping and Supply Line Upgrades
Galvanized systems corrode inward until pressure and water quality both suffer noticeably. Replacing sections or whole systems in copper or approved plastic restores flow, removes the rust, and eliminates the pinhole leaks that increasingly arrive without any warning.
Plumbing Inspections and Condition Reports
A methodical review of supply, drainage, fixtures, water heating, and shutoffs produces a written picture of where a building actually stands. Owners use these reports for budgeting, for sales, and for deciding what genuinely needs attention this year.

FAQ's
How long do copper water pipes last?
50 years or more is common, though water chemistry, velocity, and installation quality move that considerably. Type L outlasts thinner Type M, and 35+ years across San Francisco, CA has shown Malcolm Plumbing & Mechanical which runs fail first.
What is a good water pressure for a house?
Between 50 and 70 psi suits most homes and most fixtures. Below 40 the shower feels weak, and above 80 you are steadily shortening the life of every appliance, supply hose, and fill valve connected to the system.
How do I stop my drains from clogging so often?
Keep grease and food solids out of the kitchen line, fit strainers everywhere, and avoid flushing anything beyond waste and tissue. Where clogs persist despite all that, the drain itself usually has a slope, vent, or pipe condition problem.
What is the difference between repiping and spot repairs?
Spot repairs address one failure and make sense when the rest of the system is sound. Repiping replaces entire runs and becomes the better value once leaks start appearing repeatedly, since each individual repair buys progressively less time.
Why do my faucets sputter after work on the water main?
Air entered the system while it was open, and it clears with running each fixture for a few minutes. Sputtering that persists beyond that, or comes with discolored water, suggests debris has lodged in an aerator or cartridge.
Should a shutoff valve be exercised periodically?
Yes. Opening and closing valves once or twice a year keeps them from seizing in place, and it identifies the ones already failing. Discovering a seized main shutoff in the middle of an active leak is a genuinely bad moment.
What plumbing should be checked before a remodel?
Existing supply and drain condition, vent arrangement, pipe sizing for the new fixtures, and shutoff locations. Finding out mid project that a wall contains a cast-iron stack in poor condition is an expensive way to learn about it.
Do I need a permit to move a sink or toilet?
Relocating fixtures alters drainage and venting, so yes, permits normally apply. Malcolm Plumbing & Mechanical handles the permitting alongside the work for remodels throughout San Francisco, CA, which keeps the project properly documented for any future sale or refinancing.
Why Choose Us for General Plumbing Service
Several Repairs in One Visit
Trip charges and scheduling gaps make single item calls the most expensive way to maintain a building. Handing over the whole list at once lets us arrive with the right parts and clear everything in one properly planned visit.
Problems Flagged Before They Escalate
While we are working, we look at what else is nearby: corroded connections, tired supply hoses, valves that no longer turn. Telling you now, without pressure to act immediately, is worth considerably more than discovering it during an emergency.
Consistent Crews Who Know Your Building
Sending the same people back means somebody already knows where the shutoffs are, how the system is arranged, and what was done last time. That familiarity saves real time and money on every subsequent visit to the same property.
Residential and Commercial Coverage
Houses, apartment buildings, offices, and retail spaces all get the same crews and the same standards. Owners with mixed portfolios particularly appreciate not needing two separate contractors depending on which category a given property happens to fall into.
Tidy Work in Occupied Spaces
Working around tenants, staff, and customers requires containment, courtesy, and a genuine effort to leave no trace beyond the repair. Floor protection, contained debris, and a proper cleanup are simply part of how the work gets done here.
Straightforward Estimates Up Front
You hear the number before the work starts, along with what would change it if something unexpected turns up behind a wall. Surprises belong in the plumbing, not on the invoice, and that principle has served our clients well.
One Call for the Long List of Small Things
Every building accumulates a list. A dripping bibb, a slow tub, a stop that will not close, a toilet that runs at night, all individually too minor to justify picking up the phone and collectively a genuine drag on how a place feels to live or work in. Malcolm Plumbing & Mechanical clears those lists efficiently for owners across San Francisco, CA, in one planned visit with the right parts on the truck, and we flag what is coming next while we are there. Send us your list through our contact page whenever you are ready, and we will take it from there.
