"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

Septic Tanks FAQs, answered by experts

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.
