I am looking for some help with my Vacuflush/Dometic 1006 head system in my 2002 300 Sundancer. The head to my knowledge was original when I purchased the boat earlier this year but it worked fine. A few weeks ago, we had a number of people on the boat so the head got a lot more use that usual. Since then I have noticed that I have lost the vacuum seal on the head. Now the head pump will run for a bit, maybe 30 seconds and then shut off. Then for the next 3-5 minutes it will be quiet and then after then the head pump will kick back on without a flush. This cycle continues as long as I have the head switch on. My first attempt at the issue was to change the seal kit and I saw the same issue. Next I replaced the foot pedal valve as well as the ball, shaft & spring and still the same issue. My last attempt what to replace the 2 plastic half clamps and stainless hose clamp. Can anyone please let me know if there is something I am missing or some other part that I can replace? Thank you in advance.
