I thought after posting my previous comment suggesting the short extension of the internal fill hose that if the hose dropped down and then up again to the top of the fresh tank there could be future winterization issues and fill issues. In effect a potential P trap could be created in that internal fill hose. So any hose extension attempt should be kept as short as possible to get the job done. Best solution is to gain access to both ends of the hose of course.....but a total PIA for many folks.
