"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company)."

"Now for the positive experience.  I called Clearwater Plumbing and left a message.  Larry returned my call within 2 hours.  Larry was very pleasant and answered all my questions.  I purchased all the material for replacing two toilets.  I just needed a quote for labor.   Clearwater Plumbing provided a very fair estimate.  I was also able to use Clearwater's coupon on Angie's List that saved me 10% on labor.  Larry scheduled to provide the service two days after I accepted their estimate.  Larry provided a two hour window for their arrival.  Tyler came to provide the work.  He called 15 mins before he arrived.  He wore shoe covers in my house which I really appreciated.  I have changed toilets before but since I had major back surgery my wife does not want me to get injured again.  I occasionally watched his work. Tyler did not waste any time installing the two toilets.  He completed the work on-time per the quote.  Tyler did a professional job and cleaned up the area when he was done.  I would definitely use Clearwater Plumbing again for any plumbing work.  I would also recommend them to all my friends."

Sump Pump Installation FAQs, answered by experts

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.
