"What started out to be a shower installment and faucet replacement turned out to be a HUGE job. During the job we found the water pressure was extremely low due to pipe corrosion and improper installation when the house was build (1952). Dave had his guys fix me up...they even had to bust up 2ft over rock in 90+ degree weather. My plumbers guys Jim and Billy were awesome. I owe them a lot for completing this for me. And they talked me through everything along the way and cleaned up every night to perfection. THESE GUYS ARE AWESOME!!! Couldn't asked for better."

Drain Cleaning FAQs, answered by experts

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

DIY plunging or drain cleaning chemicals may help minor clogs, but professional hydro jetting ensures long-term solutions.

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.
