(B Tomm) ________________________________ Message 1 _____________________________________ Time: 07:04:23 PM PST US From: "Don Hall" Subject: RV7-List: Test tank for leaks before closing it? --> RV7-List message posted by: "Don Hall" I'm doing the wonderful fun job of prosealing my first tank. Happy happy joy joy. Before I put the baffle in place to fully enclose the tank, I'm thinking about filling the tank with water and letting it sit in the cradle for a day or so to observe leaks. I figure it's going to be real dang hard to fix leaks once the baffle is in place. Any cons to doing that? It seems like an obvious step but I haven't heard of it being done. I suppose I'd have to go through some trouble to make sure to dry it out. I think just dumping the water and maybe applying a little hair dryer action would be enough. Another thought: Is there anyway to test the capacitive senders before closing it in? ****************************************** Don Hall N517DG (registered) rv7 wings http:\\donka.net\rv7project.html ****************************************** ________________________________ Message 2 _____________________________________ Time: 07:25:32 PM PST US From: Charlie England Subject: Re: RV7-List: Test tank for leaks before closing it? --> RV7-List message posted by: Charlie England Don Hall wrote: >--> RV7-List message posted by: "Don Hall" > >I'm doing the wonderful fun job of prosealing my first tank.

Problem is, gas can find its way through places the water can't.... I toyed with the idea of using gas, but the thought of 20+ gal of gas in a *very* open container stopped even me.

I did and have no leaks. Most that have leaks that I remember reading about has to do with not putting a big enough bead on the skins prior to installing the final baffle. If I had to do it again, I would counter sink the skin where the tank baffle meets a little deeper to better allow for proseal between the rivet and the skin. Some of my rivets did not end up nice and flush, but they don't leak so I'm called it good.
