"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."

"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."

"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."

"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."

"Jaspe (?) and his crew arrived right on time and immediately began the job.  They hand dug the trench to proper depth (12" to 18").  This resulted in filling the trench with lots of water.  They installed the rock and proper sized drain pipe with dirt straining fabric.  They, also, hooked up the shop's rain down spouts to the drain pipe.  They were very careful when working in the lawn (swamp) area.  When job was completed (one day) they cleaned the whole area, hauled away the dug up dirt/gravel and wash off the concrete pad.  The area looks better now than it did before they started.  I highly recommend Wu Construction for any drainage problems.  This is the 2nd time they have done work for us.  Job well done.

Drain Pipe Installation questions, answered by experts

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

Yes, continuing to flush a clogged toilet is not likely to break up the clog. Instead, it will continue to put pressure on the clog while filling the bowl with more water, which can potentially cause the toilet to overflow—leading to an even bigger mess. Rather than repeatedly flushing, use a toilet plunger or plumber’s snake to dislodge the clog.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.
