We had the siphoning problem last weekend in our 28DS so I was doing some searching on this forum about it and ran across this post:
FR3 30DS 2015 fresh water tank size?
The para below is a quote from the discussion link above.
BTW, FR fix for the over flow is to add a longer hose and coil it three times on top of the tank before taking it out the bottom. As explained this way the water cannot get to the point of draining by siphon.
In that post it talked about adding a longer overflow hose to the FW tank but I had a question about adding 3 coils to the new longer overflow hose. So this "coil" talked about in the para above; would that be a horizontal coil on top of the FW tank or would you want to coil the overflow hose vertically to create a Ptrap situation?
