"Gerardo was great: on time, courteous, explained and cleaned up things well. I was able to get a same-day appt. which worked out really well for me. After cleaning my clogged drain he was able to fix an old shower hot water faucet that was worn out. The only thing that would have been nice is to have a written receipt before Gerardo left the jobsite. He said his office will send me one."

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

Drain Cleaning FAQs, answered by experts

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

To keep window wells from filling up with water, you need to stay on top of maintenance. Remove debris as it fills up, and regularly loosen the gravel at the base if it’s become compacted. You can also reslope your yard to make sure water flows away from the window well (and your home’s foundation), and you can even install a window well cover to prevent debris from building up. Installing an actual drainpipe at the base of the well can also prevent window well drainage problems.

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.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.
