: We have a 6 yr old, 40 gal., gas, hot water tank. The pilot light is working and we do get hot water, usually enough most of the time. Every once in a while, (It's just me here, most of the time) if I throw in a load of wash or turn the dishwasher on and then go take a shower, there is just lukewarm water, even when turned up all the way. Sometimes, it evens turns cold. Can't understand what's happening. I had it checked once and they said the tank is working fine and it is plenty big enough and I should have enough hot water. Am I explaining this suffienctly? What do you think? Thanks for a responce ahead of time. Maryanne
SOUNDS TO ME LIKE YOUR DIP TUBE IS BREAKING DOWN, HAVE YOU NOTICED ANY WHITE PARTICLES FLOWING FROM HOT WATER TAP.IF SO, REPLACE DIP TUBE.
