"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"I recently ordered a new washer and dryer for our garage and upon delivery, I was told the washer couldn’t be installed because one valve was stuck and the other was leaking. One quick call to Rubio’s Plumbing and Robert had his guys here to replace the valves and install the washer. He also remembered that I had been meaning to replace our kitchen faucet so he said he could take care of that in the same visit. Brandon and Fernando were incredibly professional, helpful, and efficient. They switched out the valves, installed the washer, replaced my faucet, and made sure to clean up after themselves. I never hesitate to recommend Rubio’s Plumbing to any friends or family, and will continue to recommend them."

"Nothing but good stuff from this company. Adrian (owners' son) is very knowledgeable and professional. I got quotes from two other plumbers for my kitchen drainage pipe massive leak. They both wanted to open-up the floor, and one of them wanted to also break-open the walkway, due to the extremely narrow crawl space. Adrian was the only one of the three that actually took a look under the house and determined that his men could dig under the footing to get to the problem. They arrived at the time scheduled, and left 2 hours later when the job done. And when I say done, I mean the area completely cleaned-up including picking-up the old pipes. They also had to cut into the stucco to get to the vent pipe. It looks like a surgeon did it. The stucco repairman is going to have an easy repair as a result. Trust me, if you're tired of dealing with plumbers that don't care about doing a good job, you have to hire Adrian at AD3 Plumbing for any plumbing issue you have. Adolfo Perez"

"They made one mistake, they reinforced the wrong place. I was like this is wrong. You suppose to do my bathroom. It was expensive. It cost a lot more this time. They made a mistake too. Overall, they are a good company, and I would use them for the next time. The fact instead they finished in one day, the finished in three days. I have to take off from work. I was uncomfortable. Their people wasn't doing it right, and I had to supervise."

"From start to finish, Motti and Rand of Green Republic Landscapes conducted themselves like true professionals. I asked them to design a yard that would be maintenance-free, drought-tolerant and conform to the turf removal rebate rules. They turned my dull, grass-filled yard into a beautiful, usable yard. They handled everything, from the removal of the grass to conditioning the soil to reinforcing the existing fence. In addition, they installed a paver patio and pathway and DG and gravel throughout the rest of the yard. Now I have a great space for relaxing and entertaining. I couldn't be happier. I would recommend Green Republic Landscapes to anyone."

Drain Pipe Installation FAQs, answered by experts

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear.
