galvanized street elbow

[tvanwave]

I am attempting to fix the freshwater fill on my 91 AS. The solution I have come up with involves threading a 1-1/4 galvanized stree elbow into the poly tank fitting. Is there any reason using a metal street elbow on my poly fresh water tank is a bad idea?

Just be sure the threads on the galv fitting are good, a burr could tear up plastic threads. They do make nylon threaded street elbows that you should use if you can.

Thanks - a good idea. I checked Lowes and Home Depot and they dont carry them - any ideas for a supplier?

I would use brass and not galvanized, it will rust eventually.

No reason that you can't use galvanized but there are other materials available. The big box DIY store selection varies from locale so it's always hit or miss, but your local plumbing supply house should carry what you need.

There's alway McMaster-Carr. They just about anything under the Sun and have Street Elbows in brass, galvanized, stainless, aluminum, and all types of plastic. Just type what you're looking for in the "Find" box located on the upper left hand side of their homepage.

UPDATE
Nothing in 1-1/4 worked. The 2" of side to side working space forced me to another solution. I used a 1-1/4 to 1/2" reducer, then a 1/2" threaded elbow, and a 1/2" pipe barb. Ran poly tubing to the exterior water inlet and terminated with a female garden hose end. Now I hook my water supply to the new poly tubing and fill it up. The tubing slides into the old 1-1/4 opening nicely and the locking cover works. I run the hose a little less than full volume and the tank fills great. No more leaks when I fill the fresh water tank.

The outside water fill doesn't come stock with any kind of a threaded fitting so that owners won't accidentally overfill their fresh water tanks and destroy them from the pressure.

In other words — BEWARE: you may not be the only person to do that task, let everybody know the risk, including subsequent owners...

True - I did allow for this by using a slow rate of fill and monitoring the water gage. I overfilled the tank on purpose to see if my fittings held ( they did) and extra water came out the vent hole. Right - this set up brings the need for a little extra vigilance as you state but I am now able to fill my tank, with no leaks--- no other solution aside from dropping the tank seemed possible. Thanks for pointing this omission out.
