My fresh tank seems to be easier to service than yours. I also added a hatch in the center of the tank that allowed plenty of space for cleaning. Fittings for the tank, water pump, and water lines will be new.
The famous Indiana limestone provides calcium and other minerals into the aquifer where our house tap water originates. The same kind of water must be in the water supply in the wells in northern Michigan near Lake Michigan, north of Grand Rapids, where the POs parked the trailer in a deer camp. These minerals were caked over the interior, and discolored the appearance of the tank. Your fittings looked similar to mine, so that is why I am posting this information.
I used toilet bowl cleaner that had no phosphates, and had a very 'sticky' adhesion to the entire tank interior. I used a long handled soft bristle scrub brush that allowed me to reach the entire interior. The height of my tank is about 14 inches, and it is around 5 feet long, 14 inches wide. After a few very heavy applications, (especially at the depth of the water level that remained in the tank since I bought the trailer) each time leaving the cleaner on for a few minutes to work on the minerals.
The appearance of the tank revealed a slightly blue tint, and gradually over the day was completely transformed into a nice clean tank. Of course, I was careful to rinse and fill and empty with water many times. I do not want to use bleach to disinfect the tank and PEX lines because I read on the Shurflo site it could harm some of the parts within the pump. I need this pump to last a couple more years, at least. The same company makes pool cover pump we use. It has lasted already a few years.
If I did use bleach, I would isolate the pump and not use it to circulate solution through and into the PEX lines. Instead, I would use a wet vac to remove the solution and rinse water until the bleach was cleared. I am not sure yet how I would disinfect the water lines.
I removed the tank and all the copper about two years ago. I sealed all the openings of the tank and stored it in the garage. Last week I worked on PEXing the water system.
The tank was in the front of the trailer under the bench area between the twin benches for the dinette. I took out the dinette and put a queen bed in the front, with the head underneath the front window. Once I finish with the floor and shore water supply, I will be able to put the tank back into the same space as before. I will have to reinforce the tank space with a dividing panel lengthwise of the tank, across the width of the bed. I want to secure the tank to the floor with tie-downs and d-rings mounted to the floor, or build a box to hold the tank securely. I expect to use the tank quite often because we are touring Indiana state parks, and generally, they do not provide a tap for campsites.
Your tank seems to be nice and wide but the height seems restricting for hands on cleaning, but not impossible. Your addition of the hatch will be helpful. Could you add a hatch to the other side?
For a thorough cleaning, you could make a flexible mop or brush, by attaching it to a drain line snake. You could adjust the slope of the tank so that water and sediment would collect in the ends of each side, by gravity. These could be removed using a wet vac hose through the hatch on each side.
I will add some photos very soon. I posted about this project in my remodel thread, http://www.airforums.com/forums/f116...tml#post926696
I want to acknowledge that I got the idea from Smokeless Joe here on the forums.
I ordered my hatch from:
Someone who commented on my thread said it would be possible to find a hatch at a price much lower than the one I purchased. I called the company and Tom answered. He suggested all the steps I took on installing. Very nice guy.
I am enjoying reading about your project. Mine is very slow, as life permits the chunks of time needed to tackle a repair.
