have being going in one shed 5 - 7 yrs without given a bother. Valve at bottom of trough and floating rectangular ball cock.
what kind of a float goes on that ozzy.
looks a damn good idea.
i have the galvanised bowls in the shed here, they had a bar welded round them to make them stronger, but they have my heart broke, no doubt they are a good age, but im forever cleaning the dung out of them.
so ive taken to making my own drinkers.
i have to get round to finishing them, for i havnt really got started much on them yet, but the steel is there and folded along with all the parts needed.
i dont have pics yet, but its basically a rectangular shaped box, 1000mm x 500 x 150mm.
a removable lid on the top of it, a baffle plate to fix a valve ( i had intended on putting in ball valves that would be in their own housing so they wouldnt get broke, but i do like ozzys valve there.
aftert hat, there is two doors on both sides, sprung so they stay closed but easily pushed open, only ever 4 odd inches of water in it, but big enough to keep them right too.
drain valve in a bottom corner.
ill galvanise them and cut the section of the trough out of the 6" wall between the pen and the creep.
no more clipping throughs with the wheels any more.
and hopefully no more cleaning out dung.
and no more leaks.
now, i dont know what they will cost, but at a guess id say they would be a dear through, somewhere in the region of 400 each if you were selling them, there is a bit of work in them.
have the shed piped with 25mm pipe insulated with armaflex and clipped to the rafters, 20mm tail pipes down to the troughs insulated as well.
dear, but cheap in the long run imo.
