Firefox was blocking them. What a long delay. The fill valve is on a separate hose-bib that is dedicated to the chicken pen. It is plumbed off of the irrigation system. Here in Round Rock, city code requires all irrigation to have a backflow preventer of sorts -in this case it is a double-check assembly. Our hosing code also requires all house mounted hose-bibs to have hose anti-siphons pinned in place. I&#39;m a licensed irrigator in Texas so they make me know these codes.GWDeveloperhttp://www.blogger.com/profile/16909581205387250102noreply@blogger.comtag:blogger.com,1999:blog-91007708936003671.post-39595412305349270932010-07-12T14:05:28.825-05:002010-07-12T14:05:28.825-05:00A great idea! I will be constructing one of these soon.<br /><br />One issue may arise, however. The fill valve is &#39;contiguous&#39; with the house drinking water supply, yes? Meaning, that there is a chance that now and then, pressure in the line or hose reaching the bucket could force the water contents of the bucket back INTO the house drinking water system.<br /><br />The use of an &#39;anti-flowback valve&#39; at the garden hose adapter should fix that issue. Such valves, made of brass and costing under $10, can be found at Home Depot, etc. They allow water to flow only one-way, from the supply to the point of use (in this case the toilet fill valve).<br /><br />I believe these valves are called &#39;anti-siphon valves&#39; as well. They are designed to screw directly onto garden hose fittings. They can operate in any position, unlike the &#39;hanging flap valve&#39; design, also available.<br /><br />I use these valves on all of my outdoor hose bibs (faucets), so that I will never again get a mouthfull of &#39;hose water&#39; from my kitchen sink!<br /><br />Thanks for a great site. Your works are very inspiring to me!<br /><br />==GP==vastgenehttp://www.blogger.com/profile/00429176634499009713noreply@blogger.com
