I recently had a new hot water tank installed... now every time we flush the toilet we conmpletely lose hot water pressure until flush finishs filling. Any suggestions... checked and tank is installed to the correct pipes.

Was this an issue before the water tank change?

Hi Camaro:

Have you checked to see if the shutoff going into the water heater is in the fully opened position?

Another thing to check is the MAIN WATER SHUTOFF... could be that the plumber had to shut this to install the water heater. Check the main shutoff to see if fully opened.

Let us know what you find...
