So during the refit
I relocated the head
from under the v-berth to the port side of the boat
. It is about 8 inches higher and the supply hose now runs across the boat
from starboard to port.
I didn't test the head on the hard
(big mistake) and during the shakedown sail the head would not pump water
in - pumped out fine.
So I am thinking
- The seals
- There are crusties in the pump
- There are critters in the bowl passages
- The pump is about 6-8 inches higher in the boat - could it be unable to lift
- I am sure this is simple
I pull the pump out of the body and the seals
are moist and actually still lubricated. There are a few crusties on the brass disks but the sealing surfaces look fine. Add some more lube and stick it together. No joy.
I pull the supply hose and suck on it and it ain't that hard to get water
to flow. Maybe the new circuitous route
has created an air bubble. I prime it backwards. No joy.
Dammit - unspecified pump failure. Go buy an overhaul
kit SGD$65. New pump SGD$90. SGD$25 is about the price
of a beer
at an upscale hotel
here and I only have to change 4 screws, and by the way I get a new pump body with the locking feature as opposed to my old one. Guess what I bought?
Find out I didn't bring the right stubbie screwdrivers today so getting the pump out will be a problem. Never mind. Install the new pump in the old body. Same symptom - No joy - WTF!!!
I actually started pulling the cabinetry apart circumventing the need for a stubbie screwdriver but then thought...
I pull the outflow from the basin and reverse prime the pump. No joy. OK, it's ridiculous but maybe this pump can't pump up 8 inches into the air. Pull the supply line off the seacock and fill the hose with water. While holding it above the level of the pump I gave it a mighty pump and promptly sprayed water all over the ceiling - WTF?
Let me say that again - Water jetted out of the intake hose...
- Picture one shows the incorrect method of installing the Jabsco
hoses - supply on top and pump-to-basin on bottom.
- Picture two shows the hoses correctly installed.
I decided to leave the locking pump handle on but the next owner is going to get a perfectly good spare Jabsco
I am an idiot...
