"Install was on time and as described. '1st Response' did the job I expected for the water heater install. Good customer service for scheduling. Note that the Angie's list price of $799 only covers the installation of 50 gallon gas AO Smith hot water tank. Assuming you also do installation of new brass fittings, new flex lines and new expansion tank (which you should probably all do with the new water heater) it will cost an ADDITIONAL approx $500-600 (mostly labor costs). That's a competitive price but still, you should be aware that the original quote is just for the water tank install itself, nothing else. All-in-all they did a good job for a competitive price. A few months after the install, so far, I can say I would recommend them for this type of work."

"Plumber Quinn K. is first rate. He’s highly competent and happy to explain as he goes if you want. On time, pro install, cleaned up, too. Maybe more expensive than some other companies but worth it due to their responsiveness, professionalism and work warranties."

"Ron was very courteous and professional. He was very thorough and after unclogging my drain came back with three estimates for fixes. He tried to put a camera down my cleanout but couldn't get it open after trying for a while - he was trying to give me an estimate on how much longer I had left in my old cast iron pipes."

"Wu Construction did an excellent job for us. Greg estimated what work needed to be done and we scheduled it as quickly as possible. The crew was on-time, very efficient and did a really nice job keeping things as clean as possible, which is no easy task when repairs are done to a wet & muddy foundation area. A full interior perimeter drainage and sump pump system was installed to eliminate standing water in the crawl space. The crew also removed all old floor insulation and installed new R-30 insulation. The crawl space was completely cleaned up and a new vapor barrier was installed. Everything was completed as agreed upon - all at a very fair & reasonable price. The crew even installed a permanent access ladder to the area so it would be easier to get into the crawl space area. I'd highly recommend Wu Construction for any drainage or foundation work needed to your home or business. Greg, the Estimator/Scheduler and Thomas Wang, the Construction Manager were a pleasure to work with. They kept us up-to-date on everything and were true to their word. I look forward to working with them again, as needed."

Drain Pipe Installation questions, answered by experts

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.  

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

To keep your toilet from clogging, you can use less toilet paper. You can also use a liquid toilet plunger to break up any clogs and keep the toilet drain and pipes clear. When it comes to a clogged toilet, the best route is prevention by using less toilet paper and making sure the mechanisms are all working properly.

You should inspect and clean your French drain at least once per year to keep it in good working order. Regular maintenance can help identify clogs, buildup, and damage before they become bigger problems, which increases the lifespan of your drain. The frequency with which a drain clogs can depend on factors like the amount of debris, the quality of the installation, and the type of filter used. If your drain accumulates a lot of sediment, it may require more frequent cleaning. It's also a good practice to check the access and exit points after heavy storms. If you notice reduced drainage or any signs of a clog, clean the drain as soon as possible.
