"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."

"Zach unplugged our kitchen drain, but it took him three attempts to reach the plug because according to him, the plug was almost 11 feet away. He was very informative and gave good advise as to how to prevent our sink from plugging up again in the future. With regards to the Apollo Plumbing, I feel that it is one of the most reliable companies you can depend on in case of emergency."

"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."

"French drain installation along a retaining wall (75 yards). Thomas who handled the sales end of things was friendly and responsive. The crew showed up on time. They were hard working and receptive of customer feedback. They first removed the ivy that was obstructing the work area and then completed the trench on day 1 which uncovered some of the unwelcome water sources. A legacy footing drain was plumbed directly into the main french drain pipe. Perpherated pipe was dropped in on Day 2 followed by river rock, catch basins, and 3 ft dry well installation. Cleanup was done thoroughly. I would hire them again in a heartbeat."

Drain Pipe Installation questions, answered by experts

Yes, short hair can clog a drain. While you might be tempted to blame the long-haired people living with you for a clogged drain, hair—no matter the length—can combine with soap scum and leftover shampoo to create a perfect storm of sticky mess that can cause your drain to slow down. 

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.
