"Very nice very knowledgeable very reasonably priced. They came the same day I called. They moved my initial appointment forward four days because they felt my drain problem (standing water in my kitchen sink)was an emergency situation. I have only great things to say and will not hesitate to call them should I ever have another plumbing issue."

"Larry and Paul were prompt and from the offset the work was good. Problem with the toilet leaking but it was resolved after 4 attempts no fault of there's just took fresh eyes - another technician - Kelly/Tyler with the same company. I would give the company more stars however, they did the old bate and swtich., The email from Tri-Sate listed a few items which the company did not address and after 3 months of asking for the invoice and apologies from Larry that the informaiton was miscommunicated in the email, I got the short end of the stick, paying for services that were not rendered with an invocie 3 months later conveying what was done. I spent 3 months of telephone calls and apologies from them wher another plumber came out and replace the bathtub sink drain that was suppose to be done by Tri-State and charged me $300. the shower drain was not done and I still have a cast iron vent pipe which takes a while for the smell to dissipate. I paid for all the tiems to get done based upon the quote I was provided and the emails and what i got was the short end of the stick with thd bate and switch tactics!!! They give you a blank screen to sign so, be careful that you check out everything on the email is done and don't go signing any blank screens!!!"

Drain Cleaning questions, answered by experts

The first rule of plumbing is nothing but water, toilet paper, number one, and number two go down the drain. 

To prevent clogs, get yourself:

  • A compast pail where you can clean plates, drain grease, and toss scraps and paper towels. 

  • Drain screens for the shower, tub, and bathroom sink to stop hair, jewelry, toys, etc. from going down the drain.

  • Trash cans for everything that shouldn’t go down the drain, like dental floss, hygiene products, and cat litter.

P.S.: If you do drop your priceless ring down the drain, take a deep breath, and then follow these steps to retrieve jewelry from your drain.

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
