Posts: 160 04/16/08 12:42:41	Tags : None I have a two cabin pullman, #633. I am changing the forward sanitation hoses. I was able to remove (by cutting it off) the hose from the head to the holding tank I am not able to do the same with the hose from the holding tank to the macerator. I am looking for suggestions on how to get these hoses off. Do you think it is necessary to change the hose from the deck pump out to the macerator. If so, how do you do it? Do you think it is necessary to change the hose from the macerator to the through hull (ball valve)? Thanks for you help.

The effective ID was reduced to less than 1/2 the inside diameter! So I would definitely look at replacing it. As Vela42 indicated, you are in deep enough to go all the way.

My hose in the aft head was 10' with vent hose at 8' 466-2 cabin

Cut vertically down the hose making sure you do not cut the barb. The hoses came off with almost no work. Replacing the hoses with a lot of liquid soap and a 1850 watt hair dryer made short work of the rest. I still need to get a hose from the macerator to the ball valve, looks like 1'' or perhaps 3/4". Does anyone know? Also, how do you get to the bottom of the deck outlet to replace the pumpout hose. I thought that I would get a coupling with the correct barb and replace the hose where it is convenient. Any suggestions. I will do the aft head next but should be easy given the access.
