"I walked into my basement on Saturday afternoon to discover a pool of water on the floor.  Looking at the walls I traced it back to right above the window that sits below my kitchen sink.  I popped the paneling off the top of the window box and immediately saw that the galvanized pipe leading from the sink drain to the stack had corroded and a hole had formed.  Frantic because it was 4pm on a Saturday and I knew I couldn't use my kitchen sink or dishwasher until I got this fixed (no easy task with two toddlers to keep up with), I jumped onto Angie's List looking for a plumber with Saturday hours and a good rating. 
I called McDonagh and was told they could have someone at my place in an hour.  Todd showed up at 5:30 and immediately got to work.  Patrick (the owner) showed up with his son Nolan shortly thereafter to take a look and get Todd some parts off of his truck.  We gave Nolan a piece of the pizza my kids were having for dinner as an apology for interrupting his Saturday too.  Patrick came back with a price estimate that seemed fair to me for emergency short-notice service on a Saturday night.  Todd replaced the entire section of pipe from the sink drain to the stack and was finished and out the door by 7:30, leaving us with a fully functional kitchen again. 
Huge thanks to Patrick and Todd (and Nolan) who really saved the day for us.  These guys are absolute professionals and really saved us from some major inconvenience.  Would absolutely recommend and use them again.

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks FAQs, answered by experts

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain.
