Sanitizing my fresh water tank

[Mogulite]

I have a 2004 Tropi-Cal and attempted to sanitize my fresh water tank. I mixed the bleach and water to put in, but couldn't figure out how to get it into the tank.

The spot where I attach the hose to fill the tank cannot be used. Is there another inlet somewhere that I'm missing? Or do I have to buy a pump to insert it through the normal fresh water fill ?

Thanks,

Steve

On my dolphin there I can pump it out of a bottle by setting the levers to "pump to tank".

Another way is to put the bleach water mixture directly in the freshwater hose using a funnel (and nitril gloves since I usually spill some). Then hook the hose up and fill it. You can get about 1/2 gallon of mixture in a 50' hose. You normally have to have the hose disconnected at both ends and have the end opposite the one you are pouring into at about the same height. When it's full attach to motorhome then to supply. Easier with 2 people.

I had a similar situation when winterizing my new-to-me 1995 Dolphin last fall. I ended up buying a Milescraft Inc. 1314 Drill Pump 750 on Amazon for $12,used a small hose as an end piece into a bucket, and pressed on from there. I plan to sanitize my tank soon as I finish my list of to-dos using the same method.

The pump attaches to my drill and is very quick.

I used a pump to put the mixture in the tank. I did go to a seminar and the presenter stated that if your water at your home is treated water then you can fill your tank and run into your lines let it sit overnight, empty and refill and this should be sufficient. I don’t know if that is true but that’s what I have done the last couple of years. Be interested to see how others feel about it.

Putting tap water thru may flush it out but technically would not sanitize it. 50ppm is the recommended chlorine level for sanitizing.
Tap water is typically less than 4ppm.

I can access my tank under the bed in my '97 Tropical. I just unscrew the overflow hose on top of my tank and funnel some bleach in. Then fill with water as usual. Let it sit for a few days and drain.

Buy yourself a 2-inch bulkhead fitting with a snap-on or screw on gasketed cap. Get the appropriate sized hole saw and drill a hole in the top of your tank, install the bulkhead fitting, which is easy enough to do, and you have a hole to pour your sanitizer, or Chlorox, in. Other than that, what I did at first was take a hand pump similar to the winterizing pump, shift the tank over to fill, and pump in the proper amount of solution. I then added enough water to fill the tank about halfway, drove around a bit, pump water through my lines and into the grey water tank until the fresh water tank was empty, and then rinsed it out with clean water until, using a tropical fish test kit, I no longer detected chlorine. Done.

If you have your pump switch turned on inside when you turn your handle 2 down position it should suck the water in through support all the way to the right just make sure your pump switches on inside hope this helps

Exactly, select the Inlet to Pump position.
