"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!"

"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."

Septic Tanks FAQs, 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.

Yes, a septic tank riser can replace a concrete septic tank lid. Risers are designed to replace various types of septic tank covers, including concrete, metal, and fiberglass, to provide easier access for pumping and repairs. While a plastic riser makes future access more convenient, the initial replacement can be difficult because concrete lids are very heavy, so it is a job best left to professionals. Once installed, you will need to be cautious around the riser during yard work, such as mowing, to avoid causing damage.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.
