OK, I started this thread. So let me give you a progress report!
I basically used Joy's posts to put together a shopping list of (mostly) brass RV specific hardware.
I did end up at camping world for the quick connectors, brass pressure reducer, and brass elbows, specialty hoses and water thief. I don't think that I spent much more than the hardware stores were charging and these items are designed for RV fresh water systems.
I got the RV portable water filter many of you recommended from Wal Marts.
I also picked up the outside faucet handles & key that Joy suggested at Lowes Hardware, and a collapsible 5 gallon jug at Harbor Freight.
All I need is the 12 volt portable pump. There I have some questions.
I went to Harbor Freight and found a portable 12 volt marine/utility pump. It is very similar to the picture on Joy's post (post #7) and costs about the same amount she paid ($29). However, instead of a cigaret "lighter" plug, it has 2 battery
clips. In fact, all of the 12 volt pumps I am seeing on the internet has battery
So, my question is: can I exchange the clips for a cigaret plug?
Also, this is for use as a bilge pump. I'm hoping that the chamber where the water pumps through is stainless steel, so the quality of the water from the collapsable jug is not compromised. I'll be calling the manufacturer tomorrow to ask.
BTW, I did search for water pumps and various stores and on the internet. The Harbor Freight pump that Joy has is the least expensive.
Anyone have any other thoughts, suggestions?
Again, thanks for your help!
