My kitchen sink was backed up and I new there was some problems with the piping under the sink. I considered trying to fix itself my self but decided to call a plumber. Plumbers San Jose answered the phone when I called, unlike the 2 other outfits I called. They came to my house and undid the plumbing under the sink. It turns out there was a huge blockage of nasty smelly stuff. The clog was cleared quickly and the plumbing was put back together. They charged me the minimum service fee and nothing for parts. I was very happy.
