Customers say: Quality work

"We needed a sump pump replacement because ours was on the fritz. After calling a few places and getting nowhere, we called Drain Kings. He came out the same day and got our new pump and installed it within a couple hours. Great customer service and great value for the money. We will definitely be using them again for other plumbing needs in the future."

"When our drains backed up late on a Sunday evening we were panicked. Bono's Blockage responded right away and came out faster than expected. The technician, Dave was fantastic—very knowledgeable and super dog friendly! They got everything flowing smoothly again in no time. Unbelievable customer service!"

"In the last few years, we've been getting huge puddles of water all over our basement floor. Never happened before. Some stretched all the way across the floor. Took hours of work with a shop vac to suck it up and days for the floor to dry. In mid-September, we hired Once & Done Waterproofing. They had the lowest price and specialize in our kind of problem. Work was completed in just one day and very tidily done. Very hard-working crew. But it was a leap of faith waiting to see if that work would be successful. Didn't rain for weeks after the sump pump system was installed beneath our basement floor. Weâ ve now had two really heavy rains. The floor remained bone dry after each of them. A little bit of water still did come in at the base of the outside basement entrance, as expected, but it got no further than the drain they installed in the floor at the door. The real test may not come until next springâ s monsoon season. But so far, so good. Based on preliminary results, I would not hesitate to hire them."

"The job was to put a sump pump and French drain into a crawl space off my basement. It was completed in a timely fashion. They removed all material in the crawl space and also sprayed an anti mold solution. When I called company to ask questions Jason kindly explained the answer."

French Drains FAQs, answered by experts

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.

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.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.
