"It was after business hours when I call regarding a drain issue. The owner of the company came out himself to fix the problem. Upon arrival the issue was assessed and the fix was done efficiently and quick. This was incredible customer service considering the times we are in meaning the pandemic. Pricing was fair and I would recommend their services."

"**Robert was very calm, cool, and collected!!!! I got a call from my tenant at about 1p on a Sunday afternoon, that her kitchen ceiling was leaking water. I suspected there was a plumbing issue right away, and I reached out to Robert. Instantly, Robert said he would go take a look after he completed his job across town. Heroically, Robert made it there in about 30 mins and discovered the issue was a clogged pipe, and used all his tools in his belt to help me clear the clogged drain issue. Long story short -- he fixed everything before 3p 😮😮😮 Thank you Robert!! You are the man!! I will call you without hesitation moving forward!!!"

"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!"

"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

You can pour hot water down your gutter drain to melt ice and keep ice dams from forming. If the problems persist, consider investing in heat cables to run in your gutters. Heat cables can adjust based on the surrounding temperature to keep ice thawed.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

On average, a plumber will take 30 minutes to two hours to clear a clogged drain. If the clog is located close to the drain or an access point and isn’t severe, the project will take about half an hour. If the clog is deep within your plumbing system or is a severe blockage, it can take two or more hours to remove the clog. For this reason, main line clogs tend to take longer, usually between two and three hours.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups.
