"Ed and his team are FANTASTIC! Based on the great reviews by others on AL, I called Ed and he came to inspect our home. Although he had a busy schedule, he was able to squeeze us in quickly ( we really needed it!), and the recent storm left us dry and comfy for the first time in years! The work was first rate, and when they left, you could not tell that anything had been done- the area was pristine. I would recommend Ed for all your waterproofing needs! He really lives up to his reputation!"

Septic Tanks questions, answered by experts

A septic tank should be emptied approximately once every three to five years, though this frequency will vary depending on your water usage, the size of your tank, how many people are in your home, and other factors. A maintenance plan for your septic system may be useful for professional emptying and inspection of other important parts.

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

A septic tank needs to be pumped once every three years on average. However, every septic tank has different needs, and the proper service interval for your system may be every five years, or as frequent as an annual pump-out. Consult with your installer about the proper interval and what to expect regarding the cost of septic tank pumping.
