"Countless mistakes were made in most of the plumbing work done.  I was my own general contractor, and I had to be on top of all the work that was done - particularly the plumbing work, where most of the mistakes were made.  For example:
- the gas line for our fireplace was originally run straight up through our living room floor next to the wall (not in the wall) -- simply ridiculous.
- the drain line under our shower was missing a P-trap
- when the old asbestos covered ducts were removed, lots of asbestos scraps were left lying in the crawl space that I had to clean up
- after the plumbing had been in, we had severe knocking/water hammer (required replacing the pressure regulator)
- after the rough plumbing was installed, the plumber left with the water pressure on - we arrived one hour later to find water spraying all over the unfinished bathroom from a pinhole leak in the joint next to the shower valve.  I had to immediately shut off all water -- they came back and fixed the solder joint where I pointed out the leak -- (but claimed they could not reproduce the leak).  Then, once all of the bathroom/shower was finished - the shower valve dripped when off (likely because the fix to the leak resulted in over-heating and warping the valve) -- they did not take any responsibility and blamed the valve manufacturer (Moen).  And since I bought the valve - they claimed no responsibility.  (Shower still drips today when in the off position).
- the plumber was rude to my wife in front of our inspector
- the plumber was clearly over-worked having to do over-time for a commercial job as well -- so our work was rushed, and as a result there were many mistakes that I had to find (they did fix the issues, one-by-one - I give them credit for that - but overall, the work was sloppy). 
I can understand a few mistakes, but this was simply too many.  In our experience, a more appropriate name for this business would be:  "In and Out and Back Again."  This may have come down to one individual's work -- but unfortunately, it has left a bad impression for the whole company.

"After lining up three plumbing contractors to install a kitchen faucet, a garbage disposal and fix a drainage leak, I selected Superior Plumbing to do the job because their technician seemed to have the necessary professionalism for a good job and they were also the least expensive of the three contractors I contacted. My service tech Armin was on time, cheerful, courteous and knowledgeable. It was obvious that he cared for my particular needs and he even announced that he loves his job and always looks forward to doing things right. He took almost exactly the time that was originally quoted and did an excellent job, cleaning up thoroughly before leaving. I wouldn't hesitate to use their services again. Thanks Armin."

FAQs for basement drainage channels installation projects in San Francisco, CA

Expect a well-built French drain to last 30 to 40 years. By channeling both surface- and ground-water away from your foundation, the system relieves hydrostatic pressure and helps prevent costly structural damage. Choose a pipe with a quality cloth filter to keep sediment out and extend the drain’s life. A quick annual inspection and routine cleanouts will keep water flowing freely, ensuring the system continues to protect your home for years to come.

Most French drains sit two feet below grade, but depth ultimately depends on the problem you’re solving. For puddling rainwater or snowmelt, a shallow curtain drain at lawn level often does the trick. To handle rising groundwater, pros dig deeper, down to the footing, and run the pipe beneath the basement slab. A drainage contractor will determine the optimal depth for your specific soil conditions and water issues.

A properly installed interior French drain captures water at the slab, channels it to a sump pit, and directs it safely outside, preventing basement floods before they occur. Because the pipe sits just under the floor edge, a plumber can reach it easily for cleaning or repairs. Pairing the drain with a reliable sump pump gives you the best long-term protection.

Hire a contractor who installs drainage systems every day—typically a foundation specialist, drainage contractor, experienced landscaper, or plumber with waterproofing experience. These pros understand slope, soil, and local codes, and they have the equipment to trench safely around utilities. Ask for references and photos of recent jobs to be sure they can design a system that keeps water off your foundation for decades.

Once the drain is in, patch the yard by reseeding bare spots or replacing plants the crew removed. Inside, look for ways to add value—finishing the basement or upgrading interior waterproofing while the space is open often costs less now than later. Schedule a quick annual checkup to flush sediment and confirm the pipe and sump pump are clear. Consistent maintenance ensures the drain functions properly and protects your investment.

Most policies don’t cover the cost of repairing a French drain itself, but they may provide coverage for water damage if the system fails. Coverage varies by insurer, so be sure to read the fine print or contact your agent before any issues arise. If you live in a high-risk flood zone, consider a separate flood policy to close the gap. Knowing your coverage in advance helps you budget for repairs and avoid unexpected costs.
