"Really glad i found Best Plumbing. Hired them to replace a shower pan and liked them so much that I had them replace shower doors and put in a new water heater as well. Fair pricing and always prompt, it felt like they went over and above what I was expecting. I would not hesitate to recommend Best Plumbing to anyone!"

"They arrived on time. Left the bathroom where the work was done clean. The job was done correctly and I haven't had any problems with their installation. There was a mistake in the billing - it was supposed to go to a different address and wasn't received so they added a late fee. When I called them about it they fixed it - I was happy. Note: The price charged included the cost of the new toilet, I had a sink and they were fine with installing that."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

"Thank you (American Mechanical) for the excellent service you provided. We are extremely pleased with the holding tank installation and all the extra work involved in acquiring permits, county approvals etc., all done in a very professional manner. Every thing was completed in the exact time frame that you said it would be and we are very appreciative of that. If you want your job done right the first time then I highly recommend American Mechanical for your job. Sincerely, Dick K."

Septic Tanks questions, answered by experts

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.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.
