"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

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.
