Plumbing problems range from a running toilet to a sump pump that will not keep up during a storm. These guides focus on safe homeowner checks and clear signals that it is time to call a plumber.
Gurgling from a drain or toilet is caused by air moving through the water in a P-trap when suction from a partial clog or blocked vent pulls it through. When one drain gurgles, it is usually local. When several gurgle at once, the main line or vent stack may be the problem.
Whole-house low water pressure most often comes from a partially closed main or meter shutoff valve, a failing pressure regulator, clogged aerators and fixtures, or a hidden leak reducing line pressure. Well owners should also check the pressure tank and switch.
A loud bang or thud when water shuts off is almost always water hammer—a pressure wave created when fast-closing valves (dishwashers, washing machines, solenoid valves) stop flow abruptly. Loose pipes create a different, repetitive rattling. Both are fixable.
When a sump pump hums but won't move water, the motor is running but something is blocking the pumping action—usually a jammed impeller, frozen discharge line, or float stuck in the on position. Here are the causes and what to check safely.
A sump pump running without stopping usually points to a stuck float switch, a missing or failed check valve, a high water table, or a pump too small for the pit. Here are the likely causes and safe checks.
A constantly running toilet is almost always caused by a flapper that won't seat, a chain that's too short or tangled, or a fill valve or float set too high. These are among the most DIY-friendly plumbing repairs in the home.
