"I needed two drains cleared so I went ahead and bought an Angie's List promo coupon for $99 for $200 of service and had them snake a couple drains for me and check out some other issues I was having.  The technician who came out was Joe.  He was very knowledgeable and experienced and totally fixed my problem quickly.  If I'd known the quality of service I'd get I would have called them first before attempting to snake the first drain myself (unsuccessfully, obviously). He was also very punctual which is HUGE for me because I have to drive 30 minutes to the building to meet any contractors and I don't live there so waiting around for hours is a major problem.  I'm always apprehensive about hiring contractors I haven't previously hired but these guys were fantastic.  I'll definitely be calling them for any future plumbing issues."

"I was skeptical at first of using HomeAdvisor to get more bids for work on our residential sewer lines but went ahead and accepted a connection with So-Cal Plumbing & Rooter. Jose called me immediately and his partner Alex and crew were here within half an hour. They did a thorough job diagnosing our issue and provided the most reasonable and fair bid we've seen. Once we accepted their offer, they began working straight away and returned in the morning to complete the job. We couldn't be happier with the experience and are grateful to Jose & Alex for their professionalism, honesty and thorough work. They will be our go-to plumbers from now on!"

"I purchased a water heater from Do It Right Plumbers . The tech, Chris, was on time and very thorough The installation went as smooth as could be. When the work was finished, you wouldn't have known any work had been done. It was that clean. Not only would I recommend them, but I also plan to use them in the future for my plumbing needs."

"I can’t recommend him enough. He was professional, honest, and showed up when he said he would, which is hard to find these days. He took the time to explain everything, gave me a fair price, and made sure the job was done right the first time. You can tell he genuinely cares about his work and his customers. If you’re looking for a reliable plumber who does quality work and doesn’t try to upsell you on things you don’t need, he’s your guy. I’ll definitely be calling him again for any future plumbing needs. My landlord loved my recommendation and has him working on her other properties. 👍"

"HomeX technician Eddie replaced a broken water shut off valve in the bathroom & installed a replacement kitchen faucet. He was knowledgeable, friendly, efficient & responded to my emergency call within the hour. The HomeX office & dispatcher were very friendly & helpful. This is the second time HomeX has come to my rescue to take care of my plumbing problems. I will definitely call them next time I need a plumber."

Plumbing FAQs, answered by experts

Ignoring slow drains in Downey allows tree roots to damage pipes hidden in clay-heavy soil. Avoid using chemical drain cleaners, as they deteriorate older cast iron pipes. Flush your water heater annually to clear hard water sediment common in CA. Run plenty of water through garbage disposals to prevent grease buildup, and avoid overloading washing machine lines during everyday plumbing use.

Helpful?

Functional plumbing requires permits and inspections to ensure compliance with CA codes, while cosmetic updates like swapping a showerhead do not. Cosmetic projects in older Downey homes expose hidden functional issues, such as corroded pipes behind walls. Both types require strict adherence to statewide water efficiency standards. Hire a licensed contractor to handle required permits and manage overlapping local requirements safely.

Helpful?

Opening walls during plumbing repairs in Downey exposes unpermitted prior work requiring mandatory correction. You face additional expenses for licensed asbestos and lead paint abatement in pre-1980 homes. Breaking concrete to access slab leaks adds significant labor and restoration expenses. Extensive tree root damage and overlapping regional sewer regulations also introduce unforeseen expenses. Install water softeners to prevent hard water from ruining new CA fixtures.

Helpful?

You must choose between copper and PEX materials for re-piping to handle hard water in Downey. Decide whether to route new pipes through walls or break concrete for slab foundation repairs. Choose trenchless or open-cut excavation for sewer repairs to preserve your landscaping. You must also approve the installation of seismic gas shutoff valves and water softeners to meet strict CA regulations during plumbing upgrades.

Helpful?

Discolored water and low pressure strongly indicate failing galvanized pipes in older Downey homes. Warm spots on your floor or unexplained water bills point to patched slab leaks needing proper repair. Repeated sewer backups signal severe root intrusion in clay soils. Look for non-standard pipe configurations under sinks, which reveal unpermitted plumbing work. Replace failing water heaters affected by hard water scale throughout CA.
