When I went to repair the fitting from the bottom of the freshwater tank that the pump intake hose hooks too...I thought I'd flush the tank out...

To my amazement, I couldn't find any drain petcock! The manual says to pump the water out when winterizing! What engineer designed that!

I removed the cover plate where the large threaded drain plug is located, but found that the plug is only partially accessible - like the tank has shifted slightly so you can't get a wrench on the plug! The plug is in good shape, and looks like new...maybe they were using a better grade plastic 30 years ago!

Question Fresh water tank problems

Hi everyone:

I have a 1983 34 Limited and my problem is the 1 1/2 elbow that draws water from the tank. It's cracked and Airstream do not have them anymore. They referred me to Camper Repair in AL 205-665-2531. They were not very helpful call several times and he said he didn't have any where he looked and said he had 5 warehouses and as much as said didn't have any.

The elbow is grey (discontinued) the hose is 1/2" ID and the thread is 5/8" OD fine. Can any one tell me where to buy this.

Fresh water tank problem resolution.

Try McMaster-Carr for the fittings you need. They are a giant hardware store for industry. They'll sell the smallest item to anyone. They stock almost a half million different items in many quantities.

They have threaded plastic elbows, nipples and bushings. They also have an 800 number you can get on the web to get more info or to order.

Yes, old posts certainly do pay!

Thanks so much for the advice on the freshwater tank plug. We thought we had a huge repair job before our weekend camping trip, but it was quite simple and cheap. The former owner of our Excella had just plugged a leak with silicone on the outside tank. Apparently, he didn't check the Airstream Forum!

Thanks again,
Al & Sandy

The petcock on my '04 28'CCD is leaking around the mounting flange.
Is the petcock mounted to the tank or is it mounted to an external cover? Because if it is a cover then I have a leak into the space between the tank and the cover.
The Lovin' Oven is an 04 28' International CCD.
It follows where the F150 Supercrew leads.

Finally dried off the plug and hole, applied teflon paste to plug. Screwed plug in tank using a 1/2" bolt with a 3/4" head, held with a visegrip. After plug was well seated. I put a 2-1/4" (I think) screw type radiator hose clamp around the outside of the tank's drain. Not too tight, just enough to squeeze the drain around the plug. That hose clamp has a lot of squeezing power.

If the plug is screwed in too tight, it could crack the drain. Big trouble.

It's held now for a year.

Thanks for the help. I had the exact same problem with a leak, had to make a tool to get the plug out, then I gooped it up, put it back in. Will check for leaks tomorrow.

new variation on plug failure

I noticed a leak in my '92 tank and found it was coming from the original plug- yellow with a hex socket for removal. I took it out and it appeared sound, but did not fit well in the tank opening. After reading this post and a trip to the local hardware store, I think my plug has shrunk in all dimensions!!! It is loose in a new 1 1/2 inch PVC female threaded fitting, and the thread pitch has changed in a manner that makes the threads closer than they should be. When I tried to screw the plug into the tank, it got tight, but not because of the taper, but because of the improper thread pitch. I purchased a new 1 1/2 inch plug and it was tight in the tank drain hole. I think this could cause a very insidious problem- plug looks good but is actually dimensionally to small to ever seal properly. I will be getting a new plug with the hex fitting since the standard hardware store plug with the raised square wrench fitting will not allow the cover to be replaced.

6 years and still going huh? Tonight I filled the tank on our new-to-us '91 excella by using the auto fill feature. Stepped outside into a small lake of water dripping from the pan.

My first thought was sheer dread thinking the tank was above one or two of the axles . Some pokin' and I find it should drop out from between axle 2 and 3 so I decided to look around here on the forum and see if any one has dropped one. Now I find this thread and will be keeping my fingers crossed that it's a bad drain plug and I don't have to pull the tank. Perhaps I will be able to sleep tonight instead of worrying about dropping that huge tank.

I need to bring this thread back from the dead again...

My white nylon freshwater petcock is fractured like so many others on this forum (and this thread). I have removed the two screws holding it in, but the petcock refuses to come out of the tank. I can rotate it a bit, but that's all. What am I missing? Do I need to pry it off with a large screwdriver or is there some trick to removing it?

Thanks for your time.

I am also having fits with the valve as well. The original valve started leaking where the line between the valve and the tank was crimped onto the valve barb. I replaced the valve and hose with a JR Products 3.8-1/2 inch drain cock part no 03182 and 1/2 inch reinforced hose from the hardware store. I had no trouble clamping the hose to the tank barb, but have tried twice to get the hose tight on the valve barb and it still leaks. I have never had so much futile work tied up in less than $5 worth of parts! What is the best type of hose and clamp to use here? It also is almost impossible to get to the clamp adjacent to the valve, so I plan to attach the hose before installing into the tank cover-even it it means expanding the hole behind the valve. Thanks, Julian H.
