Water heater not putting out enough & dip tube question...

Bradford White gas water heater
Model # MI403T6EN12

Water heater provided plenty of hot water for showers the past 10 years. All of a sudden, it now is a struggle to get through a shower with enough. Shower doesn't have a mix valve, separate valves for hot and cold. I've checked the sink mix valves and they are good. I suspect the thermostat gas valve on the water heater isn't working right. I'll probably replace the water heater since it's over 10 years old, but wanted to ask what else I can check or test?

Question # 2... Is it possible for a dip tube to be installed on the hot water outlet of the tank? I ask because while looking at the unit, I see who ever installed it has the cold supply hooked to the side labeled for hot. They did cross out the hot label and wrote cold. Just curious if they installed the dip tube on that side so it would work correctly.

Thanks in advance for your help!

When was the last time you flushed the heater?

Never. No maintenance has ever been done to it.

We've taken water heaters out of our units that were darn near full of sediment from never having been flushed. Someone else might have an idea for you but I think it might be time for a new one.

I'm going to replace it today. Can the dip tube be switched from one side to the other? It would save me from having to configure new routing of the copper lines.

UPDATE....

There was a dip tube installed where the cold feed was attached (originally marked for hot). The dip tube is broke off. If I can find a dip tube at the big box stores, I will install a new one. This water heater is in an unfinished basement, so if it bursts it won't cause damage. Might buy me another couple years.

Broken dip tube is a problem but an easy fix. Thanks for the update.
