Answers to the most frequently asked plumbing questions from Knollwood-Donnybrook homeowners.
Your main water shutoff valve in Knollwood-Donnybrook is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.
Low water pressure in Knollwood-Donnybrook homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older Knollwood-Donnybrook properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Knollwood-Donnybrook.
