"Nothing but good stuff from this company. Adrian (owners' son) is very knowledgeable and professional. I got quotes from two other plumbers for my kitchen drainage pipe massive leak. They both wanted to open-up the floor, and one of them wanted to also break-open the walkway, due to the extremely narrow crawl space. Adrian was the only one of the three that actually took a look under the house and determined that his men could dig under the footing to get to the problem. They arrived at the time scheduled, and left 2 hours later when the job done. And when I say done, I mean the area completely cleaned-up including picking-up the old pipes. They also had to cut into the stucco to get to the vent pipe. It looks like a surgeon did it. The stucco repairman is going to have an easy repair as a result. Trust me, if you're tired of dealing with plumbers that don't care about doing a good job, you have to hire Adrian at AD3 Plumbing for any plumbing issue you have. Adolfo Perez"

Customers say: True professional

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

Septic Tanks questions, answered by experts

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. 

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

If you notice a septic smell in the house, you can either call a septic system repair company or a plumber. These professionals have the proper licenses and equipment to investigate the pipes and septic tank while keeping your family safe from sewage gas exposure and raw sewage leaks. They will be able to find the problem as soon as possible and get it fixed so that your home can get back to smelling fresh again.

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.

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.
