Slow drains often start at the trap or a short run of pipe, but recurring clogs usually point to a deeper issue ? grease, hair, scale, or a partial main line restriction. We snake from the right access point, verify flow, and recommend hydro jetting when buildup lines the pipe wall instead of sitting in one plug.
Kitchen sinks see grease and food debris; showers collect hair and soap; main lines tie every fixture together. South San Francisco homes built decades apart need different approaches, and we match equipment to the line size and material rather than forcing one tool on every job.
When a backup cannot wait, we treat it as a priority dispatch. You get a clear quote before we open lines, and we explain whether the clog is local to one fixture or affecting the whole house so you know what was fixed.
Plumbing emergencies do not wait — and neither do we. Call us any time.
Every job is completed by licensed plumbers with full liability coverage.
We identify what caused the clog and recommend lasting fixes, not quick band-aids.
ASAP Plumbing Pros handles kitchen and bath drains, main lines, and sewer cleanouts for South San Francisco customers with the same licensed team. That continuity matters when a slow sink is actually a warning sign at the main.
When jetting is the right tool, we say so. When a simple snake fixes the issue, we do not upsell. You get the approach that matches the pipe condition.
Backups on holidays and weekends get the same upfront pricing standard as weekday calls. Save (415) 728-6391 for the fastest dispatch.
Donald from ASAP Plumbing was super quick and responsive. Helped me out in both San Francisco and South San Francisco. On the first occasion, he was able to unclog the drain in no time! On the second occasion, he was able to push out the "thing" that was stuck in the pipes, saving me from having to potentially replace the toilet entirely!! Super professional and easy going. 100% recommend.

I worked with Don for a few years now. Over the years, he had helped me install a toilet, garbage disposal, and fix a few emergency nasty sewer drain clogs. He never fails to fit me into his schedule. Don is one of the most honest plumbers I have dealt with. Ask your questions and he will be more than happy to help. I switched a lot of different plumbers over the years but Don is definitely my first call now. Go with DDD Plumbing San Francisco Drain Cleaning!

I’ve been using Don since his business began. Don always offers the best prices for all San Francisco draining needs. I’ve used him for faucet installations, garbage disposal, drain clogs, outdoor and indoor plumbing needs, plumbing leaks, sewer cleaning, among other services for my properties. My neighbors also raved about his coverage in the San Francisco bay area region for shower installation, water tank needs, drain cleaning, sink draining, etc. He far and away exceeds my expectations especially in the San Francisco Bay Area region where prices are exorbitant. With Don, you get bang for your buck for professional plumbing and drainage needs with free warranty for the first month! I’ll be using Don for years to come! Hey Don, time to start a loyalty program?!

If you’re looking for a reliable plumber, Don should definitely be on speed dial! I’ve been using his services for 2 years. He’s fixed everything from clogged sinks to toilet clogs and also replaced my toilet and garbage disposal. I live in an older home in San Francisco and some of those drain clogs were extremely difficult to fix but nothing Don can’t handle. Give him a call!

Don was wrapping up a job in Redwood City and heading to San Francisco, so he offered to stop by my place (on the way) immediately and get things done. I like that. He did a great job and got it done and confirmed everything was working and cleaned up before he left. I honestly don’t know the going rate for such work, so I cannot comment on the “good value” button, but I was very satisfied. He was OK with being paid with cash. That’s slowly becoming a good business advantage.

Don helped with unclogging the bathtub drain. He is responsive, professional, and able to fix the drain clogged issue quickly. I'd recommend Don to others who is looking for drain cleaning/unclogging services!

Very satisfied with Don! We had a great experience with his company DDD Plumbing Emergency Drain Cleaning with an extremely tricky toilet clog. Turns out the clog was further down into the sewer and Don had to remove the toilet in order to get to it. He had all the right equipment handy and finished the job with high quality. Highly recommend.

I've worked with Donald of ASAP Plumbing several times over the past 4 years and can confidently recommend their services. He's unclogged drains, replaced kitchen sink water valves and garbage disposal, and resolved an active leak in my old rental apartment kitchen. He's prompt to respond to inquiries, shows up during the expected time window, and overall is a very friendly and personable guy.

When a drain slows or backs up in South San Francisco, you need a plumber who clears the line completely and explains why it clogged. ASAP Plumbing Pros treats kitchen sinks, tubs, showers, and main lines with professional snaking — and hydro jetting when grease or scale coats the pipe wall. That combination stops the cycle of clearing the same plug every few months.
Standing water in a shower or gurgling after the washer drains is more than an annoyance. It signals restriction that can stress joints and push waste into lower fixtures. Our hub page for drain cleaning walks through how we access lines, when jetting makes sense, and what 24/7 emergency response looks like across the Bay Area.
Customers want to know if the clog is local or on the main, how long clearing takes, and whether camera inspection is worth it after repeat backups. We answer those on the phone when we can and again on site before we run equipment.
Periodic cleaning for older homes with mature trees, long horizontal runs, or heavy kitchen use prevents holiday-weekend backups. Ask about jetting intervals if you have already snaked the same line twice this year.
Use the contact form or call (415) 728-6391 for drain cleaning in South San Francisco. Mention which fixtures are affected and whether multiple drains are slow at once so we block enough time on the schedule.
