"After clearing the clog, they explained to me that everything - the toilet, the tub and the sink are all going through the same drain and recommend that each drain be separated to the main drain from the house. I agreed (it was about time). So, they went to work on rearranging the draining system."

"I recently hired JP Plumbing to address a clogged main line drain and the experience was exceptional. John (JP), the technician, provided outstanding service from start to finish. He was punctual, arriving right on time and ready to tackle the issue. John’s honesty and transparency really stood out. He took the time to explain the problem in detail and even went the extra mile by attaching a camera to inspect the pipes. He showed me exactly where the issues were occurring, giving me peace of mind and confidence in the work he was doing. What truly impressed me was his dedication to going above and beyond. Not only did he resolve the clog efficiently, but he also provided helpful maintenance tips to prevent future issues and keep my drains running smoothly. If you’re looking for a professional who truly cares about quality and customer satisfaction, I can’t recommend John (JP) and JP Plumbing enough. This is the kind of service everyone hopes for when hiring a plumber—professional, thorough, and completely trustworthy."

Foundation Drain Installation FAQs, answered by experts

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

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.

A range of certified professionals can install French drains, from foundation specialists to plumbers. However, you’ll want to make sure that the professional has a breadth of experience installing the specific type of drain you need in or outside your home. Your contractor should also have experience with sump pumps, waterproofing, and flood-proof landscaping.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.
