is new to me and has been in storage
for the past 3 years.
I think the holding tanks
are all gummed up with sludge.
Symptoms are -
- Tank indicators have failed on both.
- After numerous flushings and pump
outs - the water
being extracted by the pump
out system is "crystal" clear with no solids being extracted.
- One tank with rated capacity of 30 gallons appears to hold only about 10 gallons - it overflows fairly rapidly when being filled by a hose through the deck
and seem to be in good condition, boat
is 6 years old but has not been used much at all. Yes, yes yes... I know that metal tanks are a big No No... but I'm stuck with it until it fails.
I really, really
don't want to remove the tank and open it up for cleaning
Is there any magic chemical which I can add to the tank to de-sludge it and wont dissolve the aluminum
I have been trying nitrates with not much joy so far. Not sure how long they take to work
Any Advice to cheer me up for Christmas
