[C320-list] Hoses for toilet

[Rich]

Hi All,

Great discussion on how to update the black water plumbing and venting. 

We purchased our 1995 SV Destiny 3 seasons ago, with many projects to tackle. Last season we were bothered by the head odors, and after some research found a product called “Sew Clean”. It is not a black water treatment, it is a black water system cleaner designed to purge uric scale which is source of odor. We used this product last fall following the instructions with good results. Essentially you pump a quart into the head and let it sit in the hose between the head and tank for awhile, then fresh water flush it into the tank and leave it there for another couple hours, then pump out the tank with a fresh water flush. 

We will probably repeat use every-other fall since after a year the odors are still minimal. Note we cruised about 7 weeks this season, and only use the head for #1. We are in the Great Lakes so fresh water flush. 

Defender lists this for about $25 for a quart, which is the amount we used. This may be a less invasive first step to try.

This allows very good access to the pump out deck fitting and the vent fitting and hoses. It was necessary to disconnect the electric plug in that upper panel on order to bevable to pull the panel off.

It seems that I have to remove the vanity cupboard above the head. To. do this firstly seems to require the removal of the two toilet vented loops and to push the hoses back down to allow the cupboard to be removed? Is there an easier way ?
