New project - Neptune - a fantasy boat project

[DrSchmidt]

I've been lazy, but finally I made some final adjustments. As mentioned above, I have added one of David's excellent snorkel valves to the WTC to avoid the creation of a vacuum by the peristaltic pump. I've added a guide rod to the flaot of the valve to dial in its position. Next is trimming.

Hello,
I just want to ask you if you , did you put any water catcher under your snorkel to catch any stray water droplets that could get sucked in through the induction pipe?

[DrSchmidt]

Actually I removed the snorkel. It's easy to see when the ballast tank is empty and to stopp the pump in time.

Oh. Was hoping to get some feedback from you if it prevents ingress of water into the WTC. I have one of those mini air pumps I took out of a broken digital sphygmomanometer that I want to try and use as a low pressure blower, unfortunately it only has the outlet nipple. No visible intake port to attach the snorkel induction tube. Plan is to attach the snorkel intake with float valve directly to the wtc then let the airpump suck the air inside the wtc to blow the ballast tank, something like on a real submarine.

I use a peristaltic pump to pump water in and out the ballast tank. So the snorkel's only job would have been leveling inside and outside pressure in case I accidentally keep the pump on too long and not only drain the water from the ballast tank but also air from the WTC, thereby creating a vacuum.

Any updates?
