What can cause the overflow pipe from my boiler to drip?

Why is my boiler condensate pipe dripping?

A boiler condensate pipe dripping could be due to a cracked heat exchanger. This can lead to mains water or the system draining into the condensate pipe and the hot water can cause the pipe joints fail. Installing a new heat exchanger should resolve this.

What happens if a boiler runs out of water?

Boiler Failure
If a boiler has enough water, the steel will never reach temperatures high enough to weaken it. In a dry fire accident, there is no water to moderate the temperature. As a result, the boiler’s steel can overheat, warp and crack at the welds.

Why does my hot water heater overflow keep discharging water?

Causes of Excess Pressure in a Water Heater
Since water expands as it’s heated, higher-temperature water occupies more volume, which, in the confines of a water heater, results in increased pressure. If the pressure increases too much, your relief valve will activate, releasing water through the drain pipe.

What is the small pipe on the side of house dripping water?

One pipe is an air conditioning condensate drain, also commonly referred to as an AC drain line. These pipes are usually white in color and are made from PVC piping. Another pipe you may find on the outside of your home is a water pressure relief valve, also known as a PRV drain line.

What causes water to leak from boiler?
