"Beau and Ryan answered all of my questions and were very friendly. They showed up within the given time frame and removed the old tank and installed the new tank quickly and efficiently. The cost did go up due to replacing the water inlet and outlet lines and the gas inlet line. New tank, might as well have new lines. 1st Response should mention in their coupon that water/gas lines will add to the cost since Beau explained that the water lines almost always have to be replaced and the new gas line is required to maintain their lifetime warranty. Code required the installation of a condensation trap which at $125 I thought was a little over priced. Overall a good experience and I would probably use them again."

"Veteran-owned business. Honest, reputable and on time for the appointment. Ross and David spent all afternoon clearing out two clogged drain spouts and replaced/repaired a badly cracked PVC pipe after hydro jetting them. They inserted a snake with a camera and showed me the problem. They also provided a veteranâ  s discount! Thank You. Brad Pesek"

"We hired them to install a 40 foot french drain. Eric was very knowledgeable and professional, not to mention a very nice person and good listener. He was punctual and he and his crew were extemely hard workers. The job functions as promised, looks great and they were very conscientious about how they left the work area neat and clean. I wish I could hire them for other projects."

"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

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

Professional tools include drain snakes, hydro jets, cameras for line inspection, and enzymatic or chemical cleaners for dissolution.

Yes, drains are one common entry point for water bugs. However, water bugs may enter your home through various locations including doors, windows, pipes, and vents. Water bugs are drawn to the dark and moist atmosphere drains provide, and can easily find their way into your home through sewer drain pipes. You can stop water bugs from entering through drains by regularly cleaning your drains and repairing faulty drainage systems.

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

The spin cycle on your washer should initiate draining, but if you still find leftover water in the washing machine tub, you may need to drain it manually. To manually drain a washing machine, you’ll need to turn off the power supply and locate the drain hose, filter, and pump. Open or disconnect these parts and let the water drain into a bucket.
