Pipe on my pool pump slowly seeps water. Is there a way for me to fix this myself or would I have to call a professional? And just recently the water flow has become inconsistent through the Jets. In the picture, The middle jet flows the strongest and the one on the right only bubbles. Could this be caused by the small leak? There is also a valve that open and closes the flow of water to the pool. When the valve is closed halfway, more water shoots through the jet on the right. Is there a special position this valve is supposed to be set at?
