There is a hand pump that is commonly used for pumping in water system anti freeze. I think that would work.

Here’s how I get the bleach into the tank; we have the same setup as you. The inlet is the same as ours and it is the only way to get water into the tank. There is a gate valve that sends the water from the hookup either to the fresh water system or to the tank.

We built a filter system that lives in the locker with the water hookup. To get the bleach into the tank we remove the second stage filter cartridge and put the bleach in the housing and then fill the tank.

Works great. Hope this helps.

It is very simple. I put the correct amount of chlor into the hose before connecting. Sanitize hose at the same time.

Coincidentally, this Memorial Day weekend, I needed to sanitize my fresh water tank and I, too, was faced with how to best introduce a chlorine bleach solution into the fresh water tank port on the side of my 27' Flying Cloud. I went to a hardware store near the RV resort I was camping at in New Hampshire and looked for a funnel with a 90 degree turn or a flexible spout. No such thing. However, I saw a decent funnel and they had flexible plastic water hoses, so I had them cut a 2' length and connected it to the funnel with a clamp (see the photo). It worked like a dream.

sanitizing fresh water

On my cutter there is only one fresh water inlet - the city water.

The fresh water tank also has a overflow valve, and a inlet preasure regulator. So it works like this.

To fill the fresh water tank - apply city water with the overflow valve
open. This allows fresh water in and air
out. When tank is full water will discharge
out the overflow hose.

To run just city water - apply city water with overflow valve closed.
As this is now a closed system what ever
head (air in tank) provides a air preasure
cussion to the system. I usually run with
only about a third of a tank of water when
on the road (less weight) and a empty tank
when in a park. The water system will
work on city water no mater how much
water is in the tank.

To sanitize - The reason your having trouble getting
bleach into the fresh water tank is the
preasure regulator. I beat this
by putting pure bleach into a small length
of hose Ive made up (with two female hose
ends) and attach to the fresh water fill,
then hook up the city water to push it
thru the regulator. Then run city until tank
overflows, then let sit overnight, then drain,
then fill and drain one more time to flush.
