"Alan came out same day within couple of hours to clear a clogged bathtub drain. Worked on it for some time, went above and beyond to get it drained but no luck' House is 50 + years old with cast iron pipes so I was not surprised when he said ones under the tub needed to be replaced. Had been giving us trouble for several years and had been getting worse. He wrote a proposal and said he could do the next day as it was too late to start that day. James the owner showed up early next morning and went over what needed to be done. Gave a fair price and Alan showed up hr or so later and got started. Worked all day bless his heart. Got drain running smoothly. It's been about 2 weeks and all still going great. Have had a number of plumbing jobs done in the past by different companies but James Degennaro was by far the best. Both he and Alan were great and professional and did great work and clean up. .Would absolutely hire again and recommend . So glad I found them. Will need more pipes replaced in future so will be keeping them in the phone book. Patricia C. in Garden Grove, Ca."

"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"I have used Phill on several occasions and pleased every time. I had a severe drain blockage from where I did not know... With lots of hard work in two 2 hr plus sessions, Phill was able to clear the drain and all is good! I would recommend Phill's Plumbing and will hire him again when needed..."

French Drains FAQs, answered by experts

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.

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.

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.
