Thanks to everyone for posting such great tips, tricks, and modifications on the forums. I thought I would contribute back to the community and post one of my own: I replaced the dealer installed 2.5 gallon water tank of my 5x8 Silver Shadow with a Reliance 2.5 gallon Aqua Pak.
By making this switch/modification, I’ve been able to accomplish several things:
- I can disconnect the Aqua Pak from the hand pump faucet and fill the tank directly from the water source. Then I reconnect it and place it under the sink. I no longer need to have a separate water container just to transfer the water from the water source only to have to pour into the gravity water inlet into the onboard water tank. No more wasted water down the side of the trailer.
- Between camping trips, I just disconnect the tank, remove the white cap, and let it air dry. No more stagnant water growing bacteria sitting at the bottom of the tank. The Aqua Pak is also easy to clean by hand. This also means I no longer have to winterize the tank.
- I can now buy a second tank so that I can always have water available. I just disconnect the empty Aqua Pak and reconnect the full-one.
- If the tank breaks for whatever reason, I don’t have to go to a specialty RV parts store to replace it.
- With this set-up, I don't need a gravity water inlet tube, overflow drain, or petcock (the valve that helps to drain the water from the tank). This has freed up some extra space under the sink for storage. I can even remove the Aqua Pak for even more storage under the sink (when I don't need the water, of course).
- I’ve also toyed with the idea of placing a 7 gallon Aqua Pak on a shelf/ledge higher than the counter/faucet outside of the trailer. I would then feed the tube from the hand pump faucet (from inside the trailer) through the gravity water inlet out to the 7 gallon Aqua Pak (outside of the trailer) and connect it. I would then be able to use gravity to my advantage without having to pump the hand pump.
These are the parts I bought from Canadian Tire:
- Reliance 2.5 gallon Aqua Pak
- Plumbshop ¾” MIP x ¾” male hose
- Plumbshop swivel adapter ¾” FIP x ¾” female hose
- PEX ¾” MIP x ½” adapter
- stainless steel gear clamp
- thread seal tape
- hose washer
This is how I connected it:
- Connect the ¾” MIP end of part 2 to the white cap of the Aqua Pak (part 1) with thread seal tape.
- Connect the ¾” male hose end of part 2 to
- the ¾” female hose end of part 3. Don’t forget to use a washer to prevent leaks.
- Connect the ¾” FIP end of part 1 to the ¾” MIP end of part 4 using thread seal tape.
- Connect the ½” adapter of part 4 to your tube leading to the faucet (mine was a ½" opening diameter but I think standard is ⅜”) and tighten using a stainless steel gear clamp.
I’m all about lower maintenance and efficiency when camping, I'm hoping the above set-up helps me to achieve that. I'll let you know how it goes when I test it out on my next camping trip. Cheers!
