"Capped an old water connection in my laundry closet and closed it into the wall, as well as changed the connection box around the drain hose to make it more flush with the wall. Looked like the water connection was never there when they got done with it, and the connection box/drain hose looked great as well. Definitely recommend!"

"I contacted California Drains because my parent's home was completely backed up to the point where dirty water was coming out from the drains inside and outside their home. They promptly answered and booked me in the same day. They were able to contain the water from continuing to come out of the drains overnight and returned the next day first thing in the morning to get the problem fixed. Price was very reasonable, and the workers were very professional. Left everything clean and drains were completely cleared. It has been months since they came and there has not been an issue since. 10/10 will highly recommend to family and friends."

"Impressed! Johnathan and Gio were so professional, courteous, and sympathetic to our situation. I had the unfortunate experience of a root intrusion in my sewage drain and these guys made it right! They worked hard and made sure we still had use of bathrooms during the project. It wasn't the cheapest but when I saw the skill level everyday, I believe I got what I paid for and this isn't something you want to be cheap on when its under the slab! Top notch all around and the attention to detail was commendable, well done guys!"

"Mr. Perez, went above and beyond to figure out the problem with my sprinkler system, and the lack of water in parts of my garden. He finally found a broken pipe. He then dug a trench to add a new pipe and to also to equalize the water pressure. He was like a “water whisperer” solving a problem that stumped other folks."

"Wanted a bid to have my 1600 square foot single family home In West Adams earthquake retrofitted. A woman from Alpha Structural called me to set up an appointment. I told her I had no idea how much this would cost and said I heard it was around $5000. She told me yes that's about right but that they are more expensive, in the $7000-$10,000 range. I asked why they were more expensive and she didn't have an answer. I expected to hear some specific industry reason but she literally had no answer other than they "just charge more for this." Why would I bother scheduling a bid when they can't even explain why they charge a premium over other companies? Maybe this woman needs better training but they lost a potential customer along the way."

"Tom and his crew arrived early on the agreed date and finished the install the next day. The crew was hardworking and professional. Tom Hollow has readily answered all of my follow-up questions and promptly fixed one area of concern re timers. Our lawn is beautiful! Tom's was not the lowest quote I received, but the scope of work he described impressed me as thorough and the cost fit the job. I will definitely call Tom Hollow at 24kt Green for other landscape projects."

Drain Pipe Installation FAQs, answered by experts

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

To keep window wells from filling up with water, you need to stay on top of maintenance. Remove debris as it fills up, and regularly loosen the gravel at the base if it’s become compacted. You can also reslope your yard to make sure water flows away from the window well (and your home’s foundation), and you can even install a window well cover to prevent debris from building up. Installing an actual drainpipe at the base of the well can also prevent window well drainage problems.

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.
