"Robert was an amazing plumber to work with. Extremely professional, knowledgeable, responsive and honest. All traits that are hard to come by in this profession. Ever since I found his business, Iâ ve never even bothered to look elsewhere. He never tries to upsell you, gives you options and always cleans up meticulously. Iâ ve recommended him to all my friends and family and they were all happy with his services. So far heâ s fixed my clogged sink, installed and repaired my garbage disposal, came immediately when my storm drain busted, and gave me quotes and advice on a tankless water heater. Hopefully I wonâ t need his services any time soon though!"

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

"We cannot express our gratitude enough for having Cornelio on the team during our comprehensive drain and sewer pipe replacement. In the midst of my recovery from a major accident that required two surgeries, we were hit with a severe plumbing issue. Every drain in our house was nearly unusable, among other challenges we encountered. Amidst all this chaos, Cornelio was a beacon of positivity. His professionalism was evident, but what stood out even more was his genuine care and concern. Every interaction was complemented with him inquiring about my well-being and eagerly awaiting updates on my recovery. Despite the project's unexpected complexities, Cornelio and his team ensured it was completed swiftly without compromising the quality of their work. If ever the need arises (though I hope we don't have any more plumbing issues for a long time!), I would hire him without a second thought. A heartfelt thank you to Cornelio and the team!"

"Francisco called me right away. He was easy to schedule with. He communicated every step of the way, showed me the options and made sensible recommendations. He replaced a broken drain pipe in my garage, replaced a kitchen sink disposal and fixed the pipe in the kitchen sink."

"Had a water leak in under the floor in my kitchen. These guys came out and solved the problem. They had to run new pipe inside the walls so they didn’t destroy my finished floor. They even patched the walls and cleaned the mess. Good service and work was done in fair amount of time"

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

"Got a note from SFPUC for massive water use for the past several days, but no clear smoking gun. Was really worried and called Francisco asking for immediate help. He was at my house in 15 minutes and walked through all the most common culprits (toilets, etc), until we heard the water running outside and found that my kids had left the hose running. Paid him for his time and will definitely be calling him the future - amazing service. Kids learned a good lesson too."

"Lalo and his team did a great job! Aaron came first and I showed him one leak near my water heater and he went directly to Home Depot and immediately fixed that problem- just as a good faith measure. Then Lalo came and the two of them talked with me about what needed to be done with several options. They gave me an estimate and I said yes. Within an hour we had three of his team working on opening up access to the areas that needed work and procuring materials. I tried to keep ahead of them moving furniture and garage stuff out of the way ( they would have done this if I hadn?t been available to do it). While they were here my wife decided she wanted some fixtures replaced and they discovered some other drain leaks and slow drains. He and his team took care of everything and would have done more if requested. Polite and helpful. They tore into the walls and ceiling to get access and they patched up and painted so you wouldn?t know anything had been done. Would I use JVM again? YES"

Drain Cleaning questions, answered by experts

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.

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’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.
