My Union nut that connects to the diverter valve has finally cracked. I was able to remove the pipe from the pump. I think the pump just does not fit flush on the diverter valve receiving end. Is it ok to have an elbow or two plumbed to the intake port of pump or does it have to be a straight pipe running into the pump from the diverter valve? Maybe I should use flexible tubing by screwing a nipple into the intake port and a if they have a nipple that attaches to the diverter valve. I have to get it fixed tomorrow so the water can circulate.
