Use of 90 elbows
Hello. This is my first project and I am having one heck of a time trying to install my valve manifold to the poly pipe. This started as a repair of the mainline manifold and now is a replacement...May I install 90 degree elbows at the valve outlet (1" FIPT) and a barb fittings at the the poly pipe (1") WITHOUT sacrificing flowrate? It is the only way I can figure out to get the manifold barbs into the 5 poly pipes. There is not enough 'play' in the ends of the poly pipe in the valve box. Thanks.
