"Woke up to my water heater spraying water like a fountain—definitely not how you want to start the day. NJ Plumbing and Heating Guys responded within 10 minutes of me reaching out, scheduled a visit right away, and showed up exactly when they said they would. Elvis was efficient, professional, and incredibly helpful. He clearly explained what went wrong and what was needed to fix it, which I really appreciated. Pricing was fair, and everything was repaired the same day. Elvis is the man—I’m super grateful for his help. I highly recommend NJ Plumbing and Heating Guys. They’ve officially become my go-to plumbers for any future needs."

Customers say: Quick response

"Was struggling to find a reliable guy to do some paver work as well as a retaining wall for my backyard for the summer. I was recommended Art to come by. He was able to get a move on things quick. He had incredible attention to detail and was in constant communication with me. Gave some great advice about water drainage with the new patio and way to prevent stagnation of water. He also gave great advice on maintaining the area to ensure the longevity of the project. Overall great job and looking forward to having him do my front walkway as well!"

"I wanted to change my baseboard heating system to central forced air system. Mike and his crew make everything ready for new furnace: new gas line to roof, disconnecting whole baseboard system and preparing drain for the new furnace. My job was done professionally with a really good price"

Septic Tanks questions, answered by experts

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.

Unfortunately, yes. If your well pump continues working when the flow of water is completely blocked, the motor will burn up. The energy has nowhere to go, thanks to the blockage, so it turns inward. The end result? A ruined well pump and a depleted bank account (once you shop for a replacement.) 

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.
