Bizarre water problems

[Boomerweps]

First time out this year.

Sanitized after dewinterizing this late spring. Had a full FW tank. Towed great.

After setting up with full hookups, flushed the toilet, normal. Checked the kitchen (only) sink. Hot water normal, cold water a slight drizzle. Checked the shower, hot & cold normal flow. Outdoor shower, normal flows. Then the toilet started barely drizzling out.
Both showers flowed normal. Used a container with shower water for flushing all weekend.
After trying a few things Saturday and draining the FW tank after discovering it overflowing (must be a bad check valve), the flow for sink hot significantly decreased and the cold ran similar to the hot, a steady flow that would take 30-45 seconds to fill a cup. FW tank refilled over night.

Here’s the strangeness. First T off the supply line after pump and city water is outside shower, tested fine two days. Water lines run front to back and come up under shower. T out there aft to toilet, forward to next T. That T supplies the shower and continues forward on that side to the sink. Shower has full flow, toilet not. Again shower has full flow, sink not. I will drain the system with low point drains this week and start over. I only had one set of pliers and did not have a large enough wrench for the low point drains to test while camping (I will add two large adjustable wrenches to the TT toolkit).

All I can figure is a couple of air locks are happening since the middle flows but two ends in different directions don’t.

That's all the free stuff the trailer builders give you. My plumbing had a pile of wood chips in it. You would think those idiot employees would have a little bit more conscience when building these units. Hate to see what's in the hot water tank.

Pulled the toilet today. Bunch of white particulate filled up the intake screen on the foot valve. I took off one hose off the foot valve at the top to try to blow air reverse flow. It was completely clogged.

Not even possible.

Suspect list includes a failed faucet and a pinched water line. That's about all. Inspect every inch of the lines to the slow faucet.
Then with water off disconnect line from faucet and using any device that can do the job extend to a bucket and turn on water pump.. (The old convert your tub to a shower device works well for this)

IF good flow. the faucet is the culprit

IT May just be something clogging the valve.. rare but can happen.

Not sure this will help any, but do be sure the by-pass valves are all the way the right way after you dewinterized. Next, be sure the sink faucet nozzle filter is not plugged up. Unscrew that and see if water flows properly without the filter there.
