Is this the holding tank vent?

Yep.? I¡¯ve had to unplug mine, too. ?(Gross).? Keep ithe tank somewhat pumped out if you plan to do some healed upwind sailing.? Steve (Rafiki).? On Mon, Oct 25, 2021 at 7:15 PM SSTECKER <stustecker@...> wrote: |

I used an extremely long heavy duty cable tie as a snake. But you need to disconnect the small hose from the chrome/sst? fitting.? That 90 degree angle in the fitting is problematic.? On Mon, Oct 25, 2021 at 7:41 PM SSTECKER <stustecker@...> wrote:

There are several ways to clean the vent line out; compressed air works well!
But, when you have the tank PUMPED OUT at the marina: have them over fill the tank several times to clear out the vent line.? Another good trick I learned when having issues with the GROCO head: have the tank emptied just before working on it! As they are pumping out the head, add some fresh water? to the GROCO BOWL ( I use the shower head and add fresh water ). It is alot easier to work on the head plumbing after it is pumped out - the pump will suck the water right out of the hoses. Daryl s/y Intuition - PSC 31 #54 |
¿ªÔÆÌåÓýNormally vent clogs happen if you let the holding tank get full and still try to use the head on an extended trip in coastal waters.?? That pressurizes the sewage and drives it into the vent.?? If you find the head pump does not easily clear the toilet and requires more than normal pressure on the downstroke, you have likely clogged the vent. ? On my PSC 31 and earlier on my Dana, I found the best way to clear the holding tank vent was to pressurize the holding tank vent from the outside.? I must caution that before you clear the vent you must make sure the holding tank has been emptied and cleaned as best as possible after the initial pump out.? ?Refill the tank with fresh water and repump several times until you get clear water out of the tank.?? LEAVE the pump out screw on access plug off for the vent clearing process to prevent creating excessive pressure on the tank when you pressurize the vent plumbing. ?You can break the tank cover otherwise. ??Nasty experience. ? Attached is the hose valve bib I put together.?? The bib size is just slightly smaller than the vent over flow hole.? I wrapped the end of the bib with rubber tape for a good seal when pressurizing?? With the tank empty and the PUMP OUT SCREW ON ACCESS OPEN, turn on the water to the hose and when the hose is fully pressurized insert the bib tightly into the holding tank vent and open the ball valve until you get full flow through the vent into the tank.?? If you don¡¯t get flow the vent is still clogged,?? I have had situations where I had to pulse the pressure several times to clear the vent. ?By closing the valve until the hose is fully pressurize and then quickly opening the valve you can ¡°water hammer¡± the vent until it is clear. ? When done, repump the holding tank dry and replace the holding tank access plug. ? Simple, effective and clean. ? ? ? Hank Davis ? 1.714.403.7305 ?
