Water & Gas Pipe Work

O’Grady Plumbing works directly with the San Francisco Water Department on your behalf to help with accuracy in locating and identifying water line breaks.

We Provides


As pipes get older they will start to corrode. When they corrode they become weak and can crack or break in an instant. If this is not addressed right away, it can cause serious damage and costly repair expenses unnecessarily to a home.

When we repair gas or water lines:

  • We first locate where the pipe is leaking, or has broken.
  • We next cut that segment of pipe out and replace it with new material.

Although a quick repair will work for most gas or water leaks, there is sometimes a more complex problem and a partial re-pipe or even a full home re-pipe is required, depending on the severity of the problem.

If you need a gas or water line tested or repaired, we are always prepared to find concealed leaks accurately. We can help you pin point a leak by using the latest in electronic leak detection systems using sonar and electrifying pipes along with a host of other tests from air testing the line to using a gas sniffer.

O’Grady Plumbing works directly with the San Francisco Water Department on your behalf to help with accuracy in locating and identifying water line breaks. These leaks may not be evident until you get your water bill. Leak detection services will help identify leaks underneath the ground, or in the walls. Once we do the evaluation we can then accurately provide you with an estimate for the repair. In some cases we can provide you with several different solutions. We offer this service for all gas and water lines.

Company Philosophy

Low and high water pressure are different problems with different root causes. In some cases both conditions exist. For instance, if you have old galvanized plumbing, there will likely be low volume, which rears its face as low pressure. In fact, the problem is low volume delivery due to rust build up in the line. When rust clogged water pipes and high pressure exist you may experience a shot of high pressure for a second or two, and then the pressure and volume fall off dramatically.

Replacing the galvanized piping with copper will resolve the more important issue, which is adequate water supply delivery. If the issue of high pressure exists you may find the water to be visibly volatile coming out of the faucet, run out of hot water quickly, and notice a rise in your water bill. Incidentally, high pressure causes the components on the faucets and valves to fail quicker costing you more money over time. Despite having low volume before, the same condition would have existed before unbeknown to you. The solution for high water pressure is to install a PRV (pressure reducing valve). When this valve is installed, you must also install an expansion tank to compensate for the thermal exchange.

When the water heater heats to compensate for the thermal expansion, now that the PRV has closed the system, and the excess pressure has no where to go. If this step is missed, the installation of a PRV will actually have an adverse effect on your water pressure, in turn causing more damage.

Galvanized piping for domestic water use is known to cause problems. For example:

  • Rust in the water line.
  • Clogging up aerators.
  • Diminishing output at the point of use.
  • Rust can also come from the water heater when the glass lining goes out, or it can come from the ductile City main in the street in some cases.
We use copper and some PEX as an option to provide you with the best water distribution-piping layout. PEX is cheaper than copper and easier to run. The incidental use of PEX in specific areas is a better allocation of material versus copper. For gas piping we use a mix of CSST (corrugated stainless steel tubing) and galvanized for above ground installs. The CSST is more costly than regular galvanized but easier to install, thus saving money on labor. You also get a better pipe install because there are very few joints to leak.
