pump/water stream?

As a newbee on forum/airstream....? have question on faucet water stream using pump system....the water stream seems to be loaded with air bubbles or foam, is this normal (water tank full) also the wall monitor for levels and battery charge condition, water levels, etc. seems to be a very general indicator with reflections in upper light port holes. (have searched past postings no luck) thanks a million jack

The air bubbles/foam could be a result of the previous owner using baking soda in the water tank to freshen it. Just rinse the tank a few times and it'll probably disappear.

Welcome from the Florida Panhandle

First off, welcome to the Forums. We're glad to have you with us.

I agree. Run a couple of tanks full of fresh water through the system. You might consider opening the outside fresh water tank petcock and let the tank drain. If possible, hook up and take a short ride with the petcock open to agitate the water in the tank. Swing back by the house, fill it up again, and take another ride.

Also drain the hot water heater as it will hold 6 gallons in the hot water side even after you drain the rest.

Another source of foam in the water is anti freeze, the pink stuff. If the trailer was winterized you have to run water through to clear it. Again if someone who did not know what they were doing and did not bypass the hot water heater you will have 6 gallons of anti freeze to get rid of.

If these suggestions don't clear it up you may want to check the input side of the pump. Any loose connection that can aspirate air will result in bubbles. I have seen cracks in the tubing cause this.

Another possibility is a tiny crack in the inlet side of the pump or plumbing. The suction of the pump will draw air in, causing bubbles for a tiny leak and spitting for a bigger one. This happened to us several years ago and it was caused by a crack in the plastic of the inlet filter (the one with the screen) of the water pump. Replacing the filter solved the problem. Most filters are clear plastic, so take a look and see if you see bubbles in there. The leak also could be in the plumbing between the tank and the filter.
Good luck!

i think the sizes are listed here:
http://www.airforums.com/forums/38905-post1.html

and i would try a plumbing supply. the afternoons during the week seem to be slower here and the counter help will have more time to search for what you need.

Find a two-part epoxy to patch it with? Not a perfect solution, and one that you would want to keep your eye on, but it might get you going again...

What fitting are you describing here? I can envision any fitting on the input side of the pump that would have an 1 1/2 port. If this is on the fill side of the tank it can not induce bubbles.

sander17 posted my first reaction.

Of note, I notice a lot of bubbles while de-winterizing.

My winterizing routine consists of blowing the water out of the lines with compressed air, filling the system with antifreeze, then blowing all the antifreeze out. My Overlander weathers the season with nothing more than trapped antifreeze.

Pump/Water/stream

I guess parts in Canada are harder to come by than in US, as I've tried a number of plumbing supply Co and RV supply with no success.
I have to outlets on my fresh water tank both are 3/8 fine thread. One is to drain the tank (petcock) and the other which is 1 1/2" 90 degree angle that goes up to the pump. Between the tank and frame there is only 4" clearance so I really need a 90 degree.
The RV place tell me the gray material I'm looking for has been discontinued,.
Please give me a firm in US and I will order it from them.
Thanks for your help.
