Over time, it rusts, fills with deposits on the inside and leaks. It's also a bit awkward to work with unless you own a pipe threader. I think ACE used to have one, but they are gone. The time and effort saved using plastic will still be a positive even after a couple of "oops" with a shovel in future.</div><div id="yui_3_16_0_ym19_1_1490026082965_5849"><br></div><div id="yui_3_16_0_ym19_1_1490026082965_5897" dir="ltr">Dig trenches about a foot deep and use sch 40 PVC, at least for everything beyond a shut off valve. Don't use the thinner pipe. After all as been tested, backfill the trenches with a couple inches of sand or gravel. Oh and take photos to document where everything is buried.</div><div id="yui_3_16_0_ym19_1_1490026082965_5958" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1490026082965_5959" dir="ltr">Then when you start to dig to plant a new tree or something and hit the sand, you will know that you might want to be careful or move over a little.<br></div><div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1490026082965_5753" style="display: block;"> <div id="yui_3_16_0_ym19_1_1490026082965_5752" style="font-family: lucida console, sans-serif; font-size: 13px;"> <div id="yui_3_16_0_ym19_1_1490026082965_5751" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_ym19_1_1490026082965_5750" dir="ltr"> <font id="yui_3_16_0_ym19_1_1490026082965_5749" face="Arial" size="2"> <hr size="1" id="yui_3_16_0_ym19_1_1490026082965_5748"> <b id="yui_3_16_0_ym19_1_1490026082965_5768"><span id="yui_3_16_0_ym19_1_1490026082965_5767" style="font-weight: bold;">From:</span></b> Rick Moen <rick@linuxmafia.com><br> <b id="yui_3_16_0_ym19_1_1490026082965_5770"><span id="yui_3_16_0_ym19_1_1490026082965_5769" style="font-weight: bold;">To:</span></b> conspire@linuxmafia.com <br> <b id="yui_3_16_0_ym19_1_1490026082965_5772"><span id="yui_3_16_0_ym19_1_1490026082965_5771" style="font-weight: bold;">Sent:</span></b> Tuesday, March 7, 2017 1:10 AM<br> <b id="yui_3_16_0_ym19_1_1490026082965_5774"><span id="yui_3_16_0_ym19_1_1490026082965_5773" style="font-weight: bold;">Subject:</span></b> Re: [conspire] Watering automation: an edge case cautionary tale<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1490026082965_5786"><br>Quoting Paul Zander (<a href="mailto:paulz@ieee.org" shape="rect" ymailto="mailto:paulz@ieee.org">paulz@ieee.org</a>):<br clear="none"><br clear="none">> Since OpenSprinkler is open source, you could, in theory modify the<br clear="none">> software so the green house gets watered on a fixed schedule<br clear="none">> independent of rain.<br clear="none"><br clear="none">There's a less-convoluted way.<br clear="none"></div><div class="y_msg_container" id="yui_3_16_0_ym19_1_1490026082965_5776"><br></div><div class="y_msg_container" id="yui_3_16_0_ym19_1_1490026082965_5777">...<br clear="none"> It's all scarily bodged together and one hose leak<br clear="none">away from turning half my yard into a pond.
