"Half of my project was installing and burying a drainage line to pull water away from my home. Brandon, Sergio, and Terrence did an exceptional job! From the moment they arrived, until completion, they were very courteous and willing to explain any and all questions I had. They even installed and buried an additional drain line from my gutter downspout next to the drain line they were installing and connected it to the yardwell along with their drain line. I would definitely recommend Mount Valley based on the work and character of each of these guys. They reflect good on this company!"

French Drains FAQs, answered by experts

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

You can often unclog a garbage disposal in less than 10 minutes, though sometimes you might need longer if you’re unsure what’s causing the clog. For minor clogs, consider plunging the drain, flushing the drain with baking soda and vinegar, or using an Allen wrench to free the clog. If the clog is more severe, contact a local plumber.

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease.
