"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Septic Tanks questions, answered by experts

Another common question is, what pressure should your well tank be set at? The standard rule of thumb is to set your well tank’s pressure at 2 psi below the cut-on point of your pressure switch. So if your well is set up for a high cycle of 40/60 psi, your pressure should be set to 38 psi. If you use a low setting of 30/50 psi, you would set the pressure to 28 psi.

Yes, states and municipalities require septic tank companies to be licensed, so an unlicensed  individual or company cannot complete a septic tank installation or alteration. Most municipalities also require licenses for septic tank pumping. You should always verify that the company you’re considering for your septic tank project is properly licensed, which you can do by using Angi’s licensing search tool. You should also verify that the company is fully insured to avoid legal issues should an employee be injured on your property.

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

Yes, a septic tank can get full. If this happens, you might run into issues flushing your toilets or draining your sinks. You may also notice your pipes making gurgling noises or the smell of sewage floating around your house. Other signs of a backed-up septic tank include water pooling or fresh, healthy grass growing above your drain field.

You can check your own septic tank, but take precautions. Locate the access lid, usually buried a few inches underground, and remove it carefully. Look for the sludge and scum levels, and if they’re high, that means pumping may be necessary. Check for odors, slow drains, or pooling water around the drain field, which could indicate issues. Never enter the tank, as toxic gases can be fatal. All of that being said, a professional inspection is safer and more thorough.
