"I needed a plumber right away to replace an electric water heater at one of my rental properties, and someone at Drain City responded right away and scheduled someone to be at the property within a couple of hours. All communication was excellent, professional, accessible, and friendly! Although I was not at the property while the service took place, Richie communicated everything with me, and no complaints from my tenants. Thank you for your excellent service!"

"Had the water on/off to the washer break off, had a very minor flood… thank goodness I knew how to turn off the water to the house. Glover plumbing arrived, quickly corrected the damage, and gave me good advice, too. I knew this was not something I could do myself, and was not disappointed. Save this phone number and listing in case you need a good plumber, because this is the one you want to keep on hand. Highly recommended."

Plumbing FAQs, answered by experts

Installing a plumbing system is a project best left to professional plumbers. Plumbing systems involve tons of moving parts—water supply lines, pipes, drain lines, sewer connections, and connections to appliances like water heaters, washing machines, and dishwashers. Improper installation of your plumbing system can leave your house vulnerable to potential damages that could result in flooding or damage to your home’s foundation. While you can DIY your way through common plumbing problems like fixing clogged drains or leaky faucets, it’s highly recommended that you contact a plumbing professional for most of your plumbing-related tasks, especially installing the system. 

If you notice water coming out of the bottom of your tank or the flush handle, you obviously have a leaking tank. Water on the side of the tank can indicate cracks. Other signs include the toilet running and flushing without anyone touching the handle, needing to jiggle the handle to make the water stop after flushing, or needing to hold the handle down to empty the water tank.

Common problems include leaks, clogs, and running water. Regular maintenance prevents most issues.

It is generally recommended to schedule a professional plumbing inspection annually, though an inspection every two years may be sufficient for newer homes. The ideal frequency depends on several factors, including the age of your plumbing system, water quality (such as hardness), and any previous plumbing issues. More frequent checks are advisable for older homes or those with a history of problems. Additionally, if your property has mature trees with extensive root systems, more frequent inspections are beneficial as roots can crack sewer and water lines. Regular maintenance helps identify potential issues early, preventing costly repairs, and can include checking for leaks, inspecting connections, and ensuring pipes and fixtures are in good working condition to prolong the life of your plumbing system.

It is safe to flush the toilet even if the pipes are frozen, and this may even help clear out the pipes. But if the supply line is frozen, the toilet won’t refill itself until it’s thawed out. You can still flush by pouring water into the tank to refill it.
