Vic will the hold-n-treat pull and lift the contents of my holding tank the hose will be about 6 feet long and need to lift the output of my holding tank 2.5 feet to the PuraSan from there its is about 5 feet downhill to the through hull.. My marina is lost and I haven't been able to go down to help them with th installation. I thought the external pump I bought would do that? Tell me if I am wrong otherwise if you could call me at 609-377-0022 I would appreciate it. Bill Lentz
