I have a situation where a 13D system was to have a water supply of 55 gpm @ 50 psi from a well pump. All was good with the main house. Then, the owner decided that he wanted the guest house and barn sprinklered. We were told that they would run a 1-1/2" poly line from the house to the guest house. They (the plumber) also installed a 1" line from the guest house to the barn. This was not ideal, but it was workable. On paper everything worked hydraulically. Now, when reality was checked we find that the plumber did not install what we were told. Instead, of 55 @ 50 we find that at the barn there is only 10 psi flowing 20 gpm. No bueno. The guest house isn't much better. Fortunately, the main house is OK. It turns out that the plumber did not install the poly pipe and fittings as told. Instead, PEX, or something similar, was used with crimp fittings. The 90 ell's have no sweep to them so the water basically hits a wall before it turns. Not only were these fittings used but he put in a boat load of them for unknown reasons. Bottom line is that the water supply was destroyed.
Now the GC would like the sprinkler contractor to fix the problem by using a tank and pump. Problem is there is no room in either the guest house or the barn for a TALCO type package. The only place that there is room in either building is in the crawl space. There is no access other than a standard small access hole into the space and the buildings are all but finished. The sprinkler contractor would like to use a bladder tank if possible. I found what is called a "pillow tank" on line and it would work in our situation. The tank has an inlet and an outlet so that a fill line could be installed. Has anyone used a bladder tank for a situation like this? Where would be a good place to find one? What problems and concerns should we look out for? Both buildings are flowing 26 gpm so a 300 gallon tank would be needed.
