Pipe Bursting. Pipe bursting allows our plumbing professionals to dig two small points of access at the beginning and end of your piping system instead of digging up your entire yard.  The old line is blown apart as new pipe is pulled through it, effectively destroying the damaged line and replacing it with ABS pipe that is stronger and has a service life of up to 50 years. 


Before repairing your sewer line the most important step is expert diagnosis of the issue.  Comet Plumbing & Sewer has the latest video inspection and leak detection technology to pinpoint the precise source of any issue.  With our video inspections, you can even see inside the line for yourself.  Once diagnosed, we can show you the range of possible solutions.

Los Altos plumber. ★★★★★
I found this company in my Los Altos Yellow Pages. They checked out my hot water heater which was very noisy and recommended we change it. I never thought about buying a larger capacity water heater for our home until the plumber had mentioned it. So not only do I have a new heater but also more hot water. Now the family will be happy :)

Reliable and professional service. ★★★★★
My family and 
I just moved in, my mother was alarmed when the kitchen sink wasn't draining properly. The owner of Comet Plumbing came quickly to check the plumbing under the sink which I knew was old.

Andrew unblocked the clog and installed new pipework beneath the sink. I am very grateful,it was only $99.00 for this great service.
