Fix Running Toilets and Restore Flushing

Toilet repair and replacement services for residential bathrooms throughout McHenry, Illinois.

When your toilet runs constantly in your McHenry home, you hear water trickling into the bowl long after you flush, and your water bill climbs every month from the waste. A running, leaking, or poorly flushing toilet disrupts your household routine and wastes hundreds of gallons of water if left unaddressed. Homeowners across McHenry call for toilet repairs when flushing becomes weak, water leaks onto the floor, or the tank never stops refilling.

Cosmic Plumbing LLC repairs toilets by replacing flappers, fill valves, and flush mechanisms that cause running and leaking. If the toilet is cracked, outdated, or requires frequent repairs, we remove the old unit and install a new one with proper sealing and leveling. The work includes testing flush performance, checking for leaks around the base, and adjusting water flow for efficient operation. You get a toilet that flushes completely, stops running after each use, and operates quietly without constant refilling.

If you need a toilet repaired or replaced in your McHenry home, contact Cosmic Plumbing LLC to schedule service.

What You See After the Toilet Is Serviced

When Cosmic Plumbing LLC repairs your toilet in McHenry, we shut off the water supply, drain the tank, and replace the internal components causing the problem. For replacements, we unbolt the old toilet, scrape the flange clean, and set the new unit with a fresh wax ring and bolts. You will see a toilet that sits level, flushes powerfully, and stops refilling within seconds after each use.

After the repair or replacement, your toilet flushes completely on the first try without weak or incomplete clearing. The tank refills quickly and shuts off automatically without trickling water into the bowl. You no longer hear running water between flushes, and the floor around the base stays dry because the wax seal prevents leaks. Water efficiency improves, which lowers your monthly water usage and utility costs.

Toilet repairs typically involve replacing flappers, fill valves, or flush handles that wear out over time. Replacements require selecting a new toilet that fits your bathroom layout and meets current water efficiency standards. Cosmic Plumbing LLC removes and disposes of old toilets safely, then installs the new unit with proper sealing and alignment. The work finishes in a few hours, and the toilet is ready to use as soon as installation and testing are complete.

Typical concerns before scheduling toilet work

Homeowners in McHenry ask whether their toilet can be repaired or needs replacement, what causes running and leaking, and how new toilets compare to older models. These questions help you understand what the service involves and what results to expect.

What makes a toilet run constantly after flushing?
Most running toilets have a worn flapper that does not seal properly, allowing water to leak from the tank into the bowl. The fill valve may also malfunction, causing the tank to refill continuously without shutting off.
How do you know if a toilet needs replacement instead of repair?
We recommend replacement if the toilet has cracks in the bowl or tank, requires frequent repairs, or uses outdated flushing technology that wastes water. Older toilets often perform poorly compared to modern water-efficient models.
How long does it take to replace a toilet?
Most toilet replacements take two to three hours, including removing the old unit, cleaning the flange, installing the new toilet, and testing for leaks and proper flushing. Additional time may be needed if the flange requires repair.
Why does water leak around the base of my toilet?
Leaks around the base usually mean the wax ring between the toilet and the flange has failed, allowing water to seep out during flushing. Cosmic Plumbing LLC replaces the wax ring and reseats the toilet to stop the leak.
What type of toilet should I install if I replace my old one?
Most homeowners choose water-efficient toilets that meet current standards and provide strong flushing performance. Cosmic Plumbing LLC helps you select a toilet that fits your bathroom layout, budget, and preferences for comfort and efficiency.
