Disconnected all outgoing wires
The pump wire tripped the CB
Disconnected pump hot wire
No trip at CB
PUMP !!!???
New Flojet pump almost $200
Does Flojet repair pumps??
Thanks for all the help and support

The only parts are for the pump, none for motors. Many pump options for much less than $200.00 I carry a new spare on the coach as their failure can ruin a trip.

what brand/model did you purchase?
does it compare to a Flojet?

The Shurflo 4008 is a popular replacement water pump.  Search this Forum for many positive reviews.  The pump, strainer and "silencing kit" (white flex hoses) in my photo altogether cost about $110 (2 years ago).  Search online for best current prices.

The PO of my coach had installed a second water pump next to the original and valves to quickly switch over.  I added a switch to make it easier to switch.  Came in handy the other day when the pump was continuing to run on (probably trash in pressure switch?) and I just switched over to the 2nd pump.  A good upgrade to consider.  Sorry no pictures but should be easy to figure out.

Could you post a pic of your pump installation?  I don't see how I fill another water pump in that compartment.

Just curious....the Shurflo gives 3.0 gpm, the Flojet 4.5 gpm. Doesn't this effect things like taking a shower, etc?

Glenn,  Max shower flow rate is 1.5 gpm

If you're running off the pump most likely you're boondocking. The less rate would be beneficial since the pressure on both is regulated around 40 lbs.

Kinda tight but 2 pumps will fit.  The switch at top along with the valves on the hoses switches to either pump.

..., is there a practical limit to the number of momentary switches that can be used for one latching relay? I know there are two switches for the central light fixture in our coach, but I haven't looked closely at how they are wired.

Don,
I just read this thread, hence the delayed reply. There's no limit to the number of N.O. momentary switches for this, and like, circuits. They're wired in parallel.

Thanks Greg, that is what I figured but I was confused by the pictures showing two of these relays not realizing that the U320's have a relay for the solenoid fill valve, as well as one for water pump. Ours U270 has a manual water fill valve.

We have another latching relay in (near) the bathroom.  A switch in the bedroom and one in the bathroom turn on a ceiling light in the bathroom.  You can hear it clunck.  These are a good way to have multiple switches to control one thing. The part that makes these circuits a bit hard to figure out is that the switches close a path to ground.  The power switching is at the relay.

and latching relays consume power themselves 100% of the time they are "latched" - so I tend to avoid the big oight in the main salon and the latched relay light in the bathroom, since there are so many other ligths in the coach.  quick entry and exit, that latched switch by the door gets used, but if not connected to shore power, we don't use the "latched" lights or the microwave counter light (cant find an LED for it, only halogen)

UNLESS they are magnetic latching relays.  Magnetic latching draws no current in "ON" or "OFF" state, only draws current when changing state of switch.  I'm using a Blue Sea 7701 ML Solenoid in place of the conventional "boost" solenoid on our coach.

Do they make "lighter duty" ML relays for applications like controlling lights or water pumps?  Yes, they do!  See below for one example:

Our coach has, at  least, 4: The 3 mentioned, and one for the 3 lights in the dining/galley/front hallway, operated from stepwell and galley switches. Great to hear these switches are sinking to ground. I hadn't gotten around to checking that, but it will save me from having to pull wires for some LED dimmers that switch, via sinking. Thanks for the info, Roger. ^.^d

Getting back to the original topic...
I just received the pump today and will be going out to the coach to install. I have a question, though...
My fresh water tank is full. When I disconnect the existing pump, what do I do at the inlet? Can I shut off supply at the plumbing manifold, or is there another approach? I need a reply very soon, as it is raining, and a perfect day for this project. Thanks

Glenn, as I recall there is a valve on the forward wall of the pump bay to shut off the water from the tank to the pump.  Get a bunch of towels anyway.  There will be some spillage.

Thanks, Roger
I tried to bypass the pressure switch, hoping THAT was the problem. No go.
Looking at old pump, on the left, looks like corrosion at head of pump. I'll be taking it apart, just for grins, but think the old pump seized up. Will report back later
