Hello, water heaters have a limited life span, the tank types last about 20 years, and the tankless 10 or 12 years, at age 27 your hot water and especially any galvanized piping that is still attached is the prime suspect.

Tell me how long it takes to fill a one gallon jug from the first floor kitchen tap and how long it takes from an upstairs hot tap. we can go from there

.

Removed all Galvanize found debry at inlet and outlet cleaned replaced cold water drop pipe

Thanks, ***** ***** cold water pressure upstairs is good and just the not water is down to a trickle at all hot water fixtures upstairs, the odds are in the 98% range that there is a galvanized nipple somewhere in that hot water line or the cold water line to the water heater that got missed.

We can keep going until we get the situation sorted out

I'll relook Monday

The galvanized nipples that get missed the most are the ones behind the hot and cold water shut off valves inside the wall.. if they are there you can very often see them poking out from the wall a few inches, sometimes they have a chrome plated sleeve hiding them.

new hot water heater good hot water and pressure lost cold water pressure no galvanized pipes only at gate valve at inlet into house from city supply changing out next week only spins possibly broke with new water meter install? hopefully not water line

Hello again, if it were a bad gate valve at the inlet to the house, then *both the hot and the cold water would be low pressure, not just the hot. Does that make sense?
