Clogged sewer lines and drains can cause a lot of stress. Sludge, grease, and dirt can build up in your pipes, creating an unsanitary and impassable barrier keeping waste from leaving your home. 

This doesn’t need to be the case when dealing with clogged drains and sewer lines. There is a cost-effective way to get your pipes as clean as the day they were installed. You can have pipes like new, without the time and cost of tearing apart your home.


Hydro Jetting is an advanced technology that scrubs your pipes with high-pressure water which breaks up, eliminates and removes the sludge, dirt, grime, and grease that has attached itself to your pipes over time and use. Don’t let this grease and sludge build uptake over your home’s drains and sewer line. Avoid one of the homeowner’s most aggravating problems – a house full of stopped up and backed up toilets and clogged drains.


Hydro Jetting removes all of the grease and grime from your home’s pipes and sewer line  by blasting it away. High-pressure blasts of water will transform your dirty sludge-filled pipes into brilliant clean pipes.

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.
