Why does my hot water heater keep running cold?

This problem happens because the heat exchanger (the part that actually heats the water) takes a while to warm up. Before it fully warms up and starts heating the water, you get a short run of cold water. Then, once the heat exchanger heats up, you get a steady flow of warm water. So where does the initial blast of hot water come from?

Why is the water from my water cooler not cold?

Why do I have an airlock in my hot water pipe?

Primary Method Make sure your hot water supply is on. If the cold water runs OK, but the hot water doesn’t, or runs slowly then trickles off, then you may have an airlock, which is when air in the pipes isn’t being moved by the hot water, thereby blocking the pipe. Take a length of garden hose (about 1 foot) and some duct tape.

What happens if you mismatch your water pressure?

Why is my water cooler drip tray leaking?

It regularly needs to be emptied into the sink to prevent overflowing. Not doing so will result in the drip tray leaking.
