"The first visit was to replace my water heater. He asked how I liked my Sanyo air conditioning (wall mount deliver, condenser outdoors) I replied that there were great but they leak. He told me they could fix that. So second call was to fix my leaking air conditioners. In both cases the workers are prompt , professional , very helpful. These guys are not cheap but I think there prices are fair market value and they do great work.

Septic Tanks FAQs, answered by experts

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

The lifespan of your well casing depends mainly on the material it’s made from. Stainless steel and galvanized steel casings are designed to withstand the pressures and environment of deep-water wells but are susceptible to corrosion. Most steel casings last from 20 to 35 years, on average. PVC casing is highly durable and, if used correctly, can last up to 50 years.

Neither system is necessarily better or worse than the other, but one of the two might be better for your needs. For example, anaerobic systems are less expensive than aerobic ones and don’t use power to run. On the other hand, aerobic septic systems don’t take up as much space and are typically more efficient than their anaerobic counterparts.

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.

There are a few things that can make your drain field fail. These include driving or parking vehicles or heavy machinery on the field, excess sodium in the soil, or having a high water table. You can prevent failure by ensuring your installer checks that your chosen location is suitable for a drain field and properly maintaining your system with the help of a professional.
