R.P.S. Plumbing other known as Ribbs Plumbing Services was started by a fourth generation plumber David Ribbs. David is part of the Ribbs family which has been plumbing in the Silicon Valley since 1927. R.P.S. was started to provide a new high quality plumbing company that Silicon Valley has been missing, and one that wasn't at an outrageous cost to our clients! Quality is the number one concern for this business; from the shiny new trucks to the floor savers on our technicians, feet this is plumbing at its finest! RPS believes there is no other outfit in the valley that can charge the same amount and provide the same quality!! Of course other outfits are cheaper, but you get what you pay for with R.P.S. Plumbing!!!

"I called RPS back to look at something they fixed a year ago. They have pictures and records of what was done last year and they showed how the new leak wasn’t from last years repair. David did a great job of fixing the problem."

"Erick and Javier from Cabrillo Plumbing and Heating recently completed the installation of a new heat pump to replace my 30-year-old furnace. They were able to figure out how to install all of the new wiring and tubing in my 1902 Victorian home. Only 2 small holes were required to be made in the drywall . All of the wiring and tubes were neatly tacked down. Their work was impeccable and they were so courteous, respectful and pleasant. They were always on time and they cleaned up the area where the work was so done such that it was cleaner than when they started! The heat pump is such an improvement over my gas heater and incredibly quiet. I highly recommend Cabrillo Plumbing, Heat & Air!"

Water Softeners questions, answered by experts

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.

Yes, it is safe to bathe in yellow water. The iron or tannin content won’t harm your skin, and soap will clean you whether your water is clear or yellow. If you find bathing in yellow water problematic, you can ask a pro to inspect your plumbing and determine how to get your water clear again.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.
