Hot water is normal in the bathroom closest to the water heater. However, the hot water takes a long time to warm up in the rooms further away from the water heater. When it is hot, the temp is not as hot as before. The pressure is still good. I did flush and remove the built up salts out from the water heater. What could be the problem? Thank you.

the hot water takes a long time to warm up in the rooms further away from the water heater. How far away are we talking about. Is there a recirculating system involved? What's the temperature set at on the heater? Back to you, Tom
