Any house plumbers here? Non Valk related of course

Have a single lever Delta 1400 post 2005 monitor tub/shower valve. Have had low pressure for quite some time. Replaced the correct gray top cartridge after flushing the main valve body with cartridge removed. Still very little water pressure to the tub or shower! Removed flushed,removed flushed, removed flushed for a full 90 sec! Still very low pressure. Assume adequate flow coming from open valve body as it filled half of a draining tub by the time I came back inside from the pump house after shutting it off. Took apart and checked new valve,clean and can open cartridge valves with mouth suction. I am thinking I must have a build up of crud in the outlet site of the valve as I do have well water with salt intrusion. Do have a decent water softener in place. Do they make an auger small enough to clean the tub and shower pipes? Or is there an easier solution? "ALL" the other faucets in the house are fine and some are older than the 1400 monitor. My Mister fix-it halo has slipped badly and the wife now uses another shower on the other side of the house...Is muttering under her breath something to the affect that I need to call a "Real" plumber to fix it. Help

How about the water shut off valves, to the shower feed valve?

Anyway to test the water pressure at these valves?

Am trying a chemical solution that was offered on the General page. Look there for any further updates. Thanks

I am by no means an expert, so take this with a grain of salt.  Did you take off the screen at the faucet?  The house I am in now is the first well water house I have lived in.  Had similar situation and unscrewed the screens and more than a little sand and rocks were blocking the water flow.  The water comes into my house through the basement and my faucet was on the third floor.  Maybe something to check.
