"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

Septic Tanks FAQs, answered by experts

Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

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. 

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.

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.
