"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!"

"“Sugar Bear Plumbing” definitely lives up to its name! Plumbing is a messy job, but Lawrence definitely added “sugar” to what was a an unpleasant and stressful situation. He discovered a “slow leak” behind our middle unit’s shower wall that had caused a lot of rot & water damage. We had to replace plumbing, shower tiles, bathtub & flooring in one unit and water-damaged ceiling/drywall in the unit below. I am a small property owner in SF. My husband & I occupy one5 & and rent out two units in three-unit Edwardian, so our situation required appropriate communication with tenants & timeliness on the part of contractors. Lawrence understood, was always communicative, ensured workers showed up on time, stuck to the plan and finished the job on schedule. Sugar Bear is “not the cheapest or the most expensive” plumber out there, but Lawrence works on a flat-rate basis & really knows what he is doing, having apprenticed with his father and having been “in the business” for 25(+) years. Check out Sugar Bear Plumbing's site and video!!! Also, workers cleaned up as much as possible each day and sealed off working area. The only thing we noticed was that the tile/drywall sub-contractor was a bit messy & we had to scrape patches of dried joint compound off shower rods, floor, tub, tile, etc and had to remove white, dusty handprints from the tenants’ hallway walls. But, drywall/tile installation is by definition a messy job & I suppose one can’t find/clean every little spot on a tight schedule. In short, I found Sugar Bear Plumbing to be forthright, forthcoming contractors who were able to be flexible and deal with problems as they arose. I feel I found a real “gem” in Lawrence. BTW, He also took a lot of pictures & was very helpful when it came time to deal with our insurance company."

"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

Clogged pipes are one of the top signs your water heater is about to fail. Potential symptoms of excess sediment buildup include not enough hot water, leaks, unusual noises, low water pressure, and discoloration or odors in the water.

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

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.
