Blobs in fresh water tank

[STERELLIE]

I recently replaced my Aquajet water pump. But now I have a new problem... There are blobs of foul smelling sludge which quickly clog the pump screen. What is it and how should I deal with it?

You should have a drain on that tank,flush it out real good .Fill with water ,add a little bleach and flush it again.That should take care of it.Dave

Do you sanitize your tank? We live in an area where we need to winterize the water system annually. We always sanitize the water system by flushing the water lines and the freshwater tank, then put in 1/4 cup of liquid bleach, refill the tank -- run the water trhough all of the faucets, leave it sit for 48 hours, then drain flush and refill the tank again.

We also do this again sometime during the summer, and always drain the tank and refill with fresh water before each trip.

Ok where is the drain on a 1976 Airstream Sovereign ? I have had to run the pump till no more water came out and I don't like doing that BUT I can not find the drain pee cock for the fresh water tank...

OK here goes,you know where your pump is at,there should be about 3 valves there,they may be recessed in the floor.turn 1 on at a time till the water runs out on the ground.That is at least the way my Overlander is set up. Dave

I don't know about the 70's model but on my 87 I have a big plug in the bottom of my tank that can be opened to drain it real fast and completely. I found it one day because it was leaking. Had to take it out and reseal it and reinstall it. There was a trap door in the metal covering the bottom of the trailer and it was easy to access thru there. The plug was about an inch or an inch and a half in dia. and flush with the bottom of the tank. Maybe you have something like that in yours that will make flushing it easier.

Our 78 is as Bluto advises, above...

remove metal plate on underside of fresh water tank cover (4-sheet metal screws)...

plastic pipe plug will then be accessible for removal and you can flush your tank...

it's a real PAIN, to bad AS didn't install a drain cock somewhere down there when they build these models!!!

If you've got lots of 'goop' in your FW tank, this will be the only way you're going to get rid of it all...flush, flush, flush away the goop - then sanitize with some bleach in a tank full of water - overnight - then flush, flush, flush again to get rid of the bleach...fun job...!!!

So far I have bleached and flushed over and over again, but still get blobs in wire stainer. I lave reviewed the owners manuel trying to find the plate under the water tank, but still can't find it. Mexray probably has the solution. Does anyone have a 2003 34' side out???

STERELLIE, we have a 2006 34 with slide/out, and we were not shown a drain plug under the trailer, other than the petcocks just behind the rear curbside tire, and the quarter turn valve on the fresh water tank that is located curbside between two of the tires. I have to look and feel to find this one. This last valve isn’t for flushing the tank, it’s for draining the tank (slow drain). I would like to know where to find the drain plug also. Steve

My access panel (with 4 screws) and large drain on the freshwater is located on the curb side near the axle. Your right, it is not the pitcock between the axles. It is the lowest point of the fresh water tank. I can't see mine unless I get under there on my back.
If you have a manual that came with the unit, maybe it shows it in there on a drawing.
They seem to change stuff all the time so I really don't know if all the units have this plug style drain that is recessed flush in the bottom of the tank. It is actually part of the tank bottom and is not visable till you remove the small access panel thru the bottom skin. Once thru the acess panel, to remove or install mine I have to use a ratchet extention and insert the square end into the plug to turn it. To re install I use a little pipe dope on the threads of the plug and snug it down hand tight.
