Replacing a water pump on a mid bath
My pump is acting up big time.
I've tried adjusting it but it's not working correctly.

Do I need to pull the power supply out to get to the 2 far side mounting screws?
It looks that way when I pull the cover and look at it.

Have you called LD? It should be covered under the warranty,

Yes you need to pull power panel out to make an easy job of it.  Be sure you have unhooked electrical and the solar panel fuse pulled.

 That's a good idea however we're in Southern Utah until November 13.

I got it working but it sounds bad and I don't want to risk losing it without a backup or replacing it.

We are near St George and it seems like a big enough city to find one or get one delivered.

I'll need to drain the water it looks like. It would be nice to have a valve on the water line to the pump. Have you heard of anyone installing one?

I'll call the Mothership also.

Do I need to pull the entire panel or can just the lower converter power supply section be pulled?

The water line can be squeezed with a pair of needle nose visegrips, to shut off the cow of water.
We always carry a spare water pump, they never fail near a large town.
Amazon can deliver a new pump to a box somewhere near you.

Guess we must have been near you at some point, we left Utah two days ago, now looking at a white carpet coating the North Rim of Grand Canyon.

We're at Zion, then up to Cedar, and back down to Snow Valley.

I replaced mine in my 1999 this year, it was original. I unscrewed a panel below the sink, I did not have to touch the inverter. I drained the water, did not pinch a line. It was an easy job.

That's interesting.
I think they must have changed the access in later  models.

I know it's not ideal, but a city water hookup is a replacement for a water pump.

Obviously you need a campsite with city water.

On a 2021, that would be enough for me to roll with the current one until I was back at the mothership.

FWIW,

We did have electrical hook ups for most sites in this trip but not water.

For $130 I can get another pump in Hurricane, UT.

Before anything I need to remove and inspect the filter screen. It looks okay from the outside but I need to rule it out as an potential issue.

Tedeboy,
Yours looks the same as mine.  I unscrewed the converter/fuse panel and gently pushed it out a few inches.  I drained the water tank and removed the pump.  The screws on the back of the pump are awkward to access, but it can be done with a little patience.
By the way, the reason my pump sound changed, prompting me to remove it, was that the pump module was unscrewing itself from the pump motor. Since I had already ordered a new pump, I tightened the motor to the pump and kept it as a spare.

So the black cone with the adjustment hex screw loosened?
I'll check that.
Thanks

Good news.
Pentair is covering for a new pump. The technician suspects the built-in check valve switch isn't working correctly.

They are sending one to a local RV place.

I wrote long ago about ALL the screws coming out of the Mothership Vincent-installed replacement water pump under my sink and behind the power panel.  As Larry said, If you pinch off the lines you don't need to dump the water tank.  Of course you can't have big hands to get in there unless you pull out the panel, but it is possible.  However I believe the ShurFlo 4008 should have all the screws replaced by bolts with nuts, so they can't vibrate loose or even fall out!  I keep a new one, bolted together, in case I ever need to do it again.  But years later the old one is still working fine.

Interesting. It looks the same. I was able to do it. I don't remember the power panel/converter being in the way. I probably laid on the floor. Maybe the power panel/converter is bigger.

Ted, I replaced mine I had about the same access as you. I removed the power panel  and there was enough wire to sit it on the floor and pump access was easy. While I was at it, i installed a two way valve between the pump and tank so I can either turn water supply off or suck in RV antifreeze to the system for winterization.
