I am constantly getting calls from tenant saying they hold no hot water. I nick it that the hot water comes hindmost later because they finally stop calling.

Does anyone know what this is? Is my river heater too small or could it be some other hitch?

Thank you so much!
Answers:    In the first place, clean out the free loaders. Send adjectives the tenants a perceive that they will be charged for the days rent extra, that anyone not on the lease is using, day by daylight.
Then notify them that they will continue to own cold water problems if the long, one hour showers verbs. Hold the showers down to fifteen to twenty minutes and keep it this road.

Your at the mercy of these tenants and they own you against the wall, don't let this surface
replace for a bigger ones or check the temp
