"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.

"Takes for ever to get a return a call. Also took a week to get someone out for repairs. They said they would reimburse me for septic repairs and it took over 3 months for that to happen."

Septic Tanks questions, answered by experts

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field. The installation cost is so high because this is a project that requires an exceptional level of skills and expertise to execute properly.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.
