<p>Thanks for the update Paul.</p>
<p>I heat PVC and bend it too. I apply more heat to the outside of the bend. </p>
<p>You can actually see the PVC stretch as the bend is made. </p>
<p></p>
<p>How about an update on your system? Successes and "almost worked out"? Do you have a blog about your system?</p>
<p></p>
<p>all the best,</p>

<p>Thanks Harold. I had heard of the sand method too but couldn't get it to work. So made the jig. Lots of fun to make but too much time. At that point there was no turning back though...<br></br> <br></br> <cite>Harold Sukhbir said:…</cite></p>

<p>Well i think this is surely some great info. This should be posted to "Members systems introduction". Great effort on the Jig... did you make that yourself? I read that packing wet sand into PVC, then heating and bending, will give you bends without the kinks.</p>

<p></p>
<p>Jig for bending the pipe:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772241314?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772241314?profile=original" width="480"/></a></p>
<p>7" unbent pipe on the left; after bending on the right:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772241410?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772241410?profile=original" width="640"/></a></p>
<p>2" UniSeal:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772241398?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772241398?profile=original" width="640"/></a>The way I used the UniSeals in this application, the flange (at top in above photo) ends up on the outside of the tray; you push the rest of UniSeal, from the outside to the inside of the tray, through the 3" hole you've drilled in the side. </p>
<p>The narrow end of the neck of the UniSeal (at bottom in above photo) expands when you push the pipe through it. The part of the neck that's closest to the flange does not expand much or at all; but that's where the wall of the tray ends up. If the wall is too thin, then the expanded part of the UniSeal does not press against it. That's why you need a washer something like this:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772241449?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772241449?profile=original" width="640"/></a></p>
<p>UniSeal with washer in place:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772241531?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772241531?profile=original" width="640"/></a>Washer forces tank wall to rest over expanding part of UniSeal neck to make a good seal, rather than against flange, where neck does not expand.</p>
<p></p>
<p>Hope this is helpful.</p>
