Question For Peggy Hall
Peggy:
I remember some time back you mentioned here about the build up of "Urea Crystals" (?) in the sanitation hose. Well I just replaced a hose that after almost 20 years was totally blocked. The question is should something be flushed through the system periodically to prevent this buildup - if so what is it? Thanks Brian Thompson |

With mystical powers of divination I will predict the Miss Peggie will recommend
a cup of white vinegar, once a week, if the head is used frequently. Pump it partway through the system so it sits for a while, then flush it out. "Brian W. Thompson" wrote in message ...

The question is should something be flushed through the system periodically to prevent this buildup - if so what is it? Jeff's mystical powers of prediction were about 99% on target. A quart or two of clean fresh water, followed by a cupful--maybe two, but no more--of undiluted WHITE vineger in the dry mode once a week when the boat will sit at least overnight will prevent mineral buildup in the head discharge hose--and help to reduce hose odor permeation. However, there's no reason to flush only partway then wait to flush it the rest of the way through...if the head discharge hose runs downhill, it won't stay in the hose anyway...if there's a vented loop in the line, it won't do any good for the hose on the other side of the loop if it's not flushed over the top...from where it'll run downhill the rest of the way anyway. So flush it all the way the way through ...enough will cling to the hose to dissolve minerals before they can build up. Do NOT leave vinegar standing in the bowl! It won't hurt the joker valve or any other rubber parts in the toilet just passing through, but when rubber is left to soak in vinegar, it absorbs it--which will cause the seals, o-rings and joker valve to swell up and distort. Vinegar is also safe to use in a Lectra/San...in fact, will help to increase the time between electrode cleanings. It's not just urine crystals that build up, btw...it's sea water calcium carbonates. Urine crystal buildup is such a minor part of it that boats in fresh water and toilets designed to use pressurized flush water rarely if ever have a buildup problem. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://69.20.93.241/store/customer/p...40&cat=&page=1 |
