30 Gallon Water Tank - How Many Showers (approx)
I have a 30 gallon gas water tank which is about 7 years old. I rent, pay my own utilities but have to use the plumber the landlord contracts with who is onery, a "know-it-all" and a misogynist! His employees have agreed there is a problem but he overrides them, so I'm stuck between a rock and hard place.
The dial is one notch below boiling; water is hot but I never have to add cold to cool the water, which at nearly boiling I should; the tank prodcues enough hot water for one short shower; when it heats up, it sounds like a rocket about to blast off. There is never enough hot water for a bath. If I turn the dial to where it's supposed to be, the water is lukewarm.
The plumber insists: one shower is normal/adequate (as I live alone which is none of his business, my guests have to wait for the tank to heat up); he states that draining the tank, which has never been done, is fruitless, and it won't provide me more hot water; he states the [loud] noise is normal, but surely not so loud as to make me jump!
How many showers should a 30 gallon tank produce, approximately? Should a 30 gallon tank produce ONE bath? Will draining 7 years of build-up help? And the noise of heating up the hot water, shouldn't that be relatively quiet? It's frustrating having to deal with a plumber who tells the tenant he/she is wrong and he, the plumber is always right.
