"Ralph and Peter arrived on time and started the work as scheduled. They examined the problem under sink and identified leakage at the pop up assembly where the drain attaches to the sink, not in the trap. The pop up assembly and extension tail piece in the sink were removed and replaced with new parts. They checked to make sure they had all the parts first. I observed that they knew exactly what to do and worked professionally and quickly to effectively finish the job. They tested the sink and the repairs. Then asked me to inspect what they did. They instructed me on using the sink stopper correctly to prevent damage, something I thought was helpful. No issues with clean up. The job went faster than I expected. I would hire them again."

"Fast, Clean, Efficient, Feasible! This is an easy review to write when you have a professional on the job. Titan Plumbing Sewer & Drain was on site ready to swap out our old tank and install the new one. Also, was aware of new housing codes and installed an Expansion Tank. He could of easily changed the thermocouple just to get by but did not recommend doing so on a 10+ unit. Do it right once and call Titan Plumbing Sewer & Drain. We were so happy with their service! Easy to recommend them"

"Did a great job, thorough, good cleanup and were careful not to make a mess on our main floor. Came back afterwards to flash the french drain to see if that helped reduce our radon levels. Really nice guys, would highly recommend."

"Great Work! Hello. I had a French Drain installed. Water was literally sitting in my walls. The Team came over On Time. They covered spaces to keep dust from accumulating on my personal items and worked diligently to get the job done. The clean up was magnificent. With this kind of work there are rocks, dirt and concrete coming and going. You would never know they were there upon completion. I had mold that had been treated prior to this work and Mike, the owner, went above and beyond to make sure that it was taken care of. Lastly and most importantly, it's been raining for the past week and a half and I see no watery walls. I hear the new sump pump they installed doing its work. I'm very pleased with my new French Drain. Highly recommend. Thank you Mike and your Team!"

"We used to get water seeping up from the ground into our basement floor. Antonio's crew did my French drain and sump pumps about 8 years ago. We have had no water since then. I am posting this review today because I am thrilled that after Hurricane Ida drowned the entire town last night, with water in my backyard higher than my ankles, our basement is dry. Amazing."

French Drains questions, answered by experts

If your kitchen is flooding, first turn off the water supply and electricity before entering the room. Next, focus on immediate flood control by cleaning up any standing water with a sump pump or wet-dry vacuum to prevent long-term water damage to your home. Open your windows and run any dehumidifiers you have handy. Finally, call a professional plumber to help find the source of the flood and repair it.

Boiling water helps unclog a drain, but usually only with a harder abrasive such as baking soda or vinegar. On its own, it isn’t the most effective tool. In addition, you shouldn’t use boiling water if you have PVC pipes, as it can soften or melt them. Use a plunger or enlist the help of a pro if you have plastic pipes.

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters.
