"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job."

"Everyone was very professional and helpful. The only issue I have is that I find the quote for replacing the water pipe VERY expensive. Both of my parents are in the 80 s and on a fixed income."

Drain Pipe Installation questions, answered by experts

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

Yes, short hair can clog a drain. While you might be tempted to blame the long-haired people living with you for a clogged drain, hair—no matter the length—can combine with soap scum and leftover shampoo to create a perfect storm of sticky mess that can cause your drain to slow down. 

Clogged pipes are one of the top signs your water heater is about to fail. Potential symptoms of excess sediment buildup include not enough hot water, leaks, unusual noises, low water pressure, and discoloration or odors in the water.

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.

Drain clearing removes debris and clogs from drain pipes enough to allow water to drain properly. On the other hand, drain cleaning removes all of the material from the pipe so that water flows unrestricted, which is a longer-term solution. Your plumbing pro will be able to recommend the right service depending on the clog size, frequency of issues, and surrounding pipework.
