"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

Septic Tanks questions, answered by experts

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

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.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too.
