Customers say: Quality work

"Jay came through HUGE for my family & I this morning, SUNDAY morning! Main drain to street AND secondary drain both CLOGGED on a Saturday night. Jay was 1st to respond, through Angi, early Sunday morning and I m so glad he was 1st to get back to me. Jay is also an owner/operator which I like. Very friendly over the phone, also very direct in price quote. He told me he d have the problem solved for $___ which, for a Sunday I felt was reasonable, and even though the job ended up being a bit more involved/complicated and definitely more time consuming than originally expected, he actually charged me one cent less than he quoted me! Got entire house drains cleaned out as well as main & secondary drains. Was also very prompt arriving within an hour or so of initial correspondence . Jay and his technician were both very pleasant and made sure to explain to me each step he would be taking to clear the drains, taking the time to make sure I understood what was likely happening and what the likely solution would be. Jay made sure I was happy before leaving and assured me that we won t have any drain problems. We can t thank you enough for showing up within an hour of our talking and getting the job done well at the price you quoted me!! We are now washing dishes and doing laundry which, without Jay and his tech, we d still be waiting to do. Not to mention showering and basic everyday household activities that absolutely require water. Sincerely THANK YOU, Jay and Precise Plumbing!!! You came through for us BIG TIME!!!"

"Trying to sell a home from 400 miles away. An inspection told me there was a leak at the property, so I needed a plumber fast since I’m not local. The guy called me right away and went to the property to check out the problem. He called to tell me there was no leak and sent photos of the pipes under the house. No leak detected. He saved me stress , time and money checking this out so throughly and professionally! I highly recommend him for being fast, honest and professional!!"

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

French Drains questions, answered by experts

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

First, find the cleanout pipe in your yard. Unscrew the cap—you may need a wrench to do so. Then, get a drain snake. You can use a non-motorized one, but a motorized snake will make the job a little easier. Feed the snake through the pipe until it reaches the clog. Spin the snake continuously, but don’t try to feed it through the pipe anymore. Keep spinning until you feel it break the clog apart.

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.

You should inspect and clean your French drain at least once per year to keep it in good working order. Regular maintenance can help identify clogs, buildup, and damage before they become bigger problems, which increases the lifespan of your drain. The frequency with which a drain clogs can depend on factors like the amount of debris, the quality of the installation, and the type of filter used. If your drain accumulates a lot of sediment, it may require more frequent cleaning. It's also a good practice to check the access and exit points after heavy storms. If you notice reduced drainage or any signs of a clog, clean the drain as soon as possible.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups.
