I have an 86 Gibson, that I am replacing the sanitation hoses on.
I am trying to figure out how they were originally laid, and
I can't for the life of me figure it out.
The hoses that I removed were heading to a different holding tank,
one that sat off to the port side of the storage area, it was
a replacement for the original leaking aluminum tank.
I have removed both the original leaky, and its unsatisfactory
I have put in a new holding tank in the original position and can't
figure out how they had the hoses run.
As I have them planned out now, the hose have to do a 180 .
Is it better to do the 180 between the pump and holding
tank, or between the vacuum (accumulator?) tanks and the pump?
I have two heads, a vacuum tank for each, and one pump. The pump,
Accumulator tanks and Holding tank are all within close proximity,
six feet of bilge space.
I hope this doesn't sound too confusing.
Thanks for any and all help.
A 180 in ANY sanitation or vent line is never a goodplan. The
solution is new inlet and discharge fittings in location that will
allow you to come straight into the tank an st raight out of it
Look in your Yellow Pages for plastics fabricators or tank
mfrs...At least one of 'em should have the capability to spinweld a
fitting into a polyethylene tank. Use threaded plugs--available
from any hardware store--to seal the existing fittings.
Or, if you bought an "off the shelf" tank, I'd take it back. Ronco
Plastics (no relation to the VegoMatic Ronco) makes top quality
water and waste tanks for a very reasonable price and have more
than 400 shapes and sizes...and they install fittings in the sizes
and locations specified by the customer when they make the tank.
Their catalog is on their website at http://www.ronco-plastics.net.
Turnaround time is only about 2 weeks.
Your toilets are VacuFlush...and what you call "accumulator tanks"
are actually vacuum tanks. The vacuum pump sends the waste to the
holding tank. IMO, everything is crammed into too small a space for
you to end up with a system that'll be trouble-free.
What made the tank you removed unsatisfactory? Why did you move it?
'Cuz a location next to the hull is a much better place for it than
the center of the boat.
I wish we'd talked before you did all this...'twould have been a
lot easier--and prob'ly would have cost you less--to order a tank
with fittings installed in the right places. But it may not be too
late. If you'd like to discuss this one-on-one in more detail than
is practical in a discussion forum, send me a PM and I'll give you
my contact info. 'Cuz although it can be frustrating to back up and
start over now, it's always cheaper and easier to get it right the
first time than it is to do it over later.
