Fresh Water Bladder Replacement ??

[Bob Pullen HC-33 1981]

Just noticed a leak on my spare water tank:cry:. It seems like a 20 to 30 gal. black rubber original that came with Seanorita -- no mfg. markings -- see attached picture.
Would anyone know of any source for spares, that could be ordered online or on the phone?
Many thanks in advance.

who invented these smileys? where did they come from and where are they going?

Bob, I installed a Plastimo brand flexible tank in my boat last year.
http://http://cgi.ebay.com/ebaymoto...1834844QQptZBoatQ5fPartsQ5fAccessoriesQ5fGear These tanks have a PVC(?) internal bladder protected by an outer fabric cover and come in a wide variety of shapes and sizes. As far as flexible tanks go, these are on lower end expense wise. There may be a reason for this but so far mine is working well. I figure if it does spring a leak it will only be water in the bilge. If I was installing a sewage tank, or venturing off shore, I would give it some more thought. I got mine on Ebay, but it turns out that the SBO store here sells a different brand.http://http://shop.macgregorowners.com/detail.htm?fno=80&group=774
I'm afraid I can't help with the smile question .

It looks like neither of those links are functioning. Not sure what I did wrong but you should be able to find either of them.

No matter which manufacture or 'style' bladder you choose, be sure that its 'certified' for use with POTABLE water. Either FDA or NSF compliance is acceptable.
Without such certification you risk ingesting harmful 'leachables' ... polymer fragments, monomers, that can be very harmful. Most bladders you see for 'boat usage' will NOT have such certification.

The reason they eventually leak

all the time is that they do rub against something because of the water sloshing around. Don't forget to order the right fittings, including a vent. If you can, try a solid tank if you can fit one in, it'll last forever, your boat, your choice.
