Master head won't drain

Perhaps you’ve not heard of a great new invention, rubber gloves.

They make chewing your nails even harder. Not to mention picking your nose.

The master head won't drain. It fills up and then over a few days slowly drains to empty. I have run a few gallons of CLR into the bowl with no success. Just poured a gallon a muriatic acid into the bowl, don't know if its drained through or not as I had to leave.

Looks like 2" PVC piped with 90 angles under tub into engine room up to galley maid pump on starboard side engine room floor. Then through a 1" line with a siphon loop, disappears through floor along strake and re-appears in genny room to black water tank.

If I attached a line to the existing 1" line, what could I force through it to de-calcify or unclog if that is where the issue is?

Sky mentions that the old line is held up with cushion clamps every 1', so yanking it out would be a major PITA even if you could access it all. So it the procedure to abandon in place and pull through another line?

Was thinking about replacing galley maid with a new Atlantis Freedom. I'm thinking that if I have to spend $500 having it rebuilt, better $1k for new. Anyone have any experience with these?

thx

I replaced the master head with Atlantes and love it. Unfortunately they don’t sell 32 volt Atlantes any more so I also had to install a 32-12 volt converter. I’m not sure if running a 24 volt model on 32 volts would significantly reduce its life.

On the other hand, the GM heads sometimes just lose prime, particularly underway. Do you still have the 1/4 inch copper line from the seawater to the sewage side of the pump? Lossen the nut on the sewage side and see if air bubbles escape. If there’s any air in there the discharge pump just cavitates.

Also, behind the toilet is a short length of hose between the water input and the waste line. Replace that hose and it significantly improves performance.

I converted to Atlantes fresh water heads 14 years ago. I'm never going back. They just work and I don't have to ever mess with them. I have only had to remove one once to work on it. It had a nickel stuck in the macerator blades. I have no idea who was eating nickels.

The disc from a halogen light right over the head occupied my time for quite a while. It was the perfect size to flip like a butterfly valve on a random basis. ‘Toilet lids down’ was added to the before getting underway checklist. Kinda like placing your tray table in the upright and locked position.

That's because when the crap hits the fan we have to (by law) be able to get ALL of you OUT in X (I think it's three) minutes and all those tray tables down would slow the process down considerably.

Not slowing me down. I’ve evacuated three airliners in my time.
