Question DetailsAsked on 4/15/2016

Does my water heater have problem?

Since early this year, i found out that during and after my shower, the water heater was giving quite loud sound like bang, bang... I felt the water pipe is shaking. And also each time when i open any faucet (kitcken, bathroom) to hot water, it took longer before water turns hot. Not sure if the hot water got some problem or it need to be replaced. (It's a 50 gallon tank from year 2005).

Sounds like it is boiling - probably due to sediment buildup in the bottom. have you been draining off the sediment annually (or twice yearly in hard water or water sediment areas) ?

If sediment or mineral buildup is the problem, draining it down now is not likely to solve the problem but you could try it and see - but likely hardened in the tank as scale by now and not likely to flush out. You could get it acid treated by a plumber which sometimes works but with an 11 year old tank, unless stainless steel (very rare in residential use - will say on tank what kind of lining you have, probably glass or porcelain), if just flushing (draining) the tank does not solve the issue I would get a new water heater rather than sink money into it. For that size commonly $800-1400 range to replace.
