I turn on the shower and wait 4 to 5 minutes before hot water comes out of shower head.dont want to fill cesspool.help...

Got a lot of money to spend? There are options. Plumb a return line to the water heater and put in a recirculater pump, or put in an on demand flash heater in the bathroom... or move the bathroom closer to where you r water heater is.

I agree with Smoothy to install a recirculater pump see the attached PDF file below , Thanks.
