Why do I run out of hot water so fast, and can it be fixed?
Short answer
In tank water heaters the top reason is a failed lower heating element (electric) or a burned-out dip tube (any fuel type). Both are cheap fixes if the tank is under 8 years old. If it's older than 8, spend the money on a right-sized replacement instead — you'll fix the symptom and buy back another decade.
Common causes ranked
1) Burned-out lower element on electric tanks. 2) A broken dip tube dumping cold water at the top instead of the bottom. 3) A tank that's just too small for household use. 4) Sediment buildup eating capacity — a 40-gallon tank with 8 years of sediment behaves like a 25-gallon.
The 5-minute diagnostic
Run the shower until it turns cold, then feel the top and bottom of the tank. Warm top / cold bottom on electric means the lower element is dead. Both cold means the whole tank is out — check the breaker and reset the high-limit switch on top of each thermostat.
When to just upsize
If you added a bathroom, kid, or a soaking tub since the tank went in, you're outgrew it. A 50-gallon replacement is usually $200 more than a 40 and adds ~30% recovery.

How long should a water heater last in Washington?
Standard tank water heaters in the PNW last 8–12 years. Beyond year 12, the risk of a burst tank doubles every year. If yours is over 10, check for a manufacture date on the label, put a leak sensor under it, and start budgeting for replacement — a burst tank is 40 gallons on your floor in under two minutes.

How do I stop a toilet that keeps running?
A toilet that keeps refilling every few minutes has a leaky flapper 90% of the time. Drop food coloring in the tank, wait 15 minutes, and check the bowl — if the color shows up in the bowl without flushing, replace the flapper. It's a $8 part and a 10-minute fix.
