Using a Jobo forced film washer

[Photo Engineer]

Using this method is not the most efficient method of wash.

I tested it out and the chemistry is removed slowly this way. I think that stuff is caught in the lift inlet or something. But my tests do show more carryover this way than by removing the tank and washing with a hose or using a tray for prints.

not to mention laborious.

I tested it too.It only worksif done repeadiatelyfor 6 to 10 times. sticking a hose into a tankis far easier

I just repeated pour water into the tank, let it turn for 30 seconds, and empty the tank using the lift.

I repeat the process many times.
Time efficient no.
Water efficient yes.
Easier is not always better. Water resources have to be conserved in the southwest US. I rather spend the time than waste water.

The Jobo Cascade takes about 3L/min .
Jobo advises to use it for 5min, that makes 15L .

you cannoyt waste water.it recycles automatically with the weather.if ya serious, stop flushing the toilet and don't take showers or wash the car:and while ya at it;stop breathing too CO2;rememberlaugh:

You are forgetting the enormous environmental cost of transporting the water, espcially in order to support settlements in otherwise arid places.

RE waste: contaminated water might eventually evaporate and return to its origin in the grand cycle of nature, but it will no longer be viable for most uses, and has a detremental effect on nature. Don't you remember that dead fish icon on the bottles of rodinal, reminding you that discharging the liquid back to nature will have an adverse effect on marine life?

I do ;and you are right of course but, Iadmit that environmentalists are getting under my skin lately.a reasonable use of our resourcesis an admirable task, but there also needs to be a reasonable limit of saving for savings sake.slowlyrunning freshwater is the most thouroughway of washing film and paper;wrong place to conserve water for me.I'd rather skip a showernobody needs a hot shower twice a dayif it means under washed film.:confused:

 

[CatLABS]

Agreed.
For those reasons i used to flunk students in my class who left the tap running over a tray with prints so they will be "washed" and then just left for hours or even over night.

As you say being reasonable or moderate is just fine, but there is absolutly no reason to "waste" water, when you can not waste it

 

[RalphLambrecht]

the true science of washing is rarely undertood.The Nisgra Falls wont do a better job than slowly running water in the same amount of time. volume is not the issue.

I just purchased one of these from CatLABS, and I must say, after 10 years of washing films manually, it is some of the best money I have ever spent.
