FINAL UPDATE
It works. I'd taken a break to have a short 'personal pity party' and allow Nancy to take a shower (bypassed system to feed shore water directly into coach water system) and thereafter, unbypassed my plant and all was well. Great pressure too. Just got done putting all my stuff back into the bay. And now, it's 'It's Miller Time'
UPDATE 2
Okay - new pump installed - went in fine.
But... it's pulling air and water into the pump and unsure why thus far. I ran 2 gallons of water from the output of the pump, into a jug to ensure the pump was purged after installation. I've checked the strainer bowl, inlet and outlet connectors. Still about a 50/50 mixture.
The way I have this plumbed is "through" the Anderson valve. I have a feeling that perhaps I've got an issue there. Maybe an o-ring has slipped and I'm bringing in air from another port. Time to test this theory and pull the fresh water tank suction / fill line off the Anderson valve and plumb it directly to the pump to confirm.
Getting too old and fat to be spending this much time "in the hole" and in and out of the bay
Will report back later on this saga
UPDATE 1
So it was the pump. All 10 screws that connect the pump head to the motor had sheared off.
Temporarily, I replaced the pump with the tiny one that came with the Landmark I'd been carrying it as a spare. Turns out the tiny OE pump was not up to the task.
I'm on my way to a Camping World to pickup an Aquajet Variable Speed RV Water Pump, 5.3 GPM. I called and they have 2 in stock and as a member, they'll match their online price. Will update later.
ISSUE
I usually post coach modifications, not problems on the forum. Not that I never have coach problems. I have my share. But I'm a bit beside myself this week
Anyway, tonight, my water pump starting hammering like crazy, like it can't get prime. There is a lot of water in the tank but nothing getting pumped.
I noticed before this trip that one of the screws had rattled out of or broken from the pump head. Due to how I've mounted my pump in a bit of an elaborate filtration and whole-coach RO system, I wasn't able to replace this screw or the pump before this trip.
Tonight while out shopping, we had a load of clothes in the washer, washing. When we arrived back home, we found water on the floor in the main bathroom. There was a leak at the plastic nut on the end of the PEX where it connects to the toilet. Honestly, that nut wasn't very loose. I was barely able to tighten it up much more. The drip did stop though.
Minutes later, the super-loud water pump hammering began for the first time (that we've been home to hear anyway). Shortly thereafter, we lost pressure at all faucets.
I'm not tearing into it tonight, but here's a couple of theories I'll test tomorrow:
1. Obstruction between tank and pump inlet (it does go through the Anderson valve)
2. Bad pump
Fortunately, I have a lot of experience with the water system in the coach and there's an RV parts store a few miles away for a new pump if needed. So I'm pretty sure I can get this taken care of in the morning.
So, I'm unsure what to make of the water leak at the commode and whether it has anything to do with the pump. Did the pump output suddenly go to 125 PSI output? Just coincidence?
Anyone have any thoughts?
