"Dreadful experience. We had been customers of Astacio since 2015 when they installed our first tankless boiler which failed completely after 7 years and needed to be replaced in late 2022. ($10,000+) Their second one just stopped working; a dodgy board? The part is under warranty but they want almost $1,000 to replace it in the boiler; probably less than 2 hours work. I thought they used to be a good local business with ties to the community but be careful; their tankless boilers are unreliable and they'll try to rip you off when your heat goes out in the winter. So much for standing by their work. I'll never use them again."

"The upgrade of a new water heater and the removal of the old water heater seem like it was a good job. However, the plumber did too much haggling for more money. I checked the price of this job ahead of time as I always do with any work that needs to be done at my home. Parts and labor, I always need to know up front. I do not like it when any workers come off as greedy and try to insult my intelligence. I hope the work of this young man lasts. However, I would have been able to give him 5 stars, if he had chosen to fully conduct himself as a professional in the end. This plumber was paid $1700. The price I paid was completely within the range of what it cost for parts and labor to upgrade an old water heater, with a new water heater. I wish his well..."

Sump Pump Installation questions, answered by experts

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

You need a sewage ejector pump if you have appliances or fixtures that use water below ground, such as basement sinks, bathrooms, or laundry facilities. If all of your indoor plumbing connections are above ground, on the main floor or higher, gravity can do the work without a sewage ejector pump.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

If your sump pump has burnt out or malfunctioned before the end of its expected lifespan, you should be able to notice a few warning signs. Running constantly, making strange noises or vibrations, or ceasing to function altogether are all clear signs that your sump pump is due for replacement. You should also replace the sump pump if you notice any signs of incorrect installation.
