Slow hot water flow

Might be caused by a worn cartridge or parts in the faucet set. Try replacing these and clean out the oulet screen while you're there. Check relative flow in other locations as well. Did the installer change and maybe downsize any piping?

I was the installer Piping was not changed

Loss of flow is consistent throughout the house It's just as visible in the tub/shower as the kitchen

Does the new tank have those "heat saving" anti-thermosyphon valves in/near the water inlet/outlet fittings?

If it does, one of them may have gotten jammed or come loose and stuck somewhere.

HTH,

Make sure the strainers are clean. You often get sediment loose when doing that job and it can clog up strainers and other valve parts.

Other than that I like Jeff's anti-siphon valve suggestion.

I believe they do And how do I check test those ?

Couple of outlets don't have strainers, and they're just as slow.

I can't think of any "simple" way to test them other than to pick up one new one and try swapping it for what's there.

Not too hard to do if the installer used unions when the heater was installed.

Maybe someone else knows an easier way to check/test them?
