My son had loosened to lid on the pump basket the other day, (one drawback to TFP, the water is so clear the basket looks empty. Hubby thought the same before.) so I closed the valve in the hose so I could reposition it, as it was dripping. Well, I briefly turned the pump on before realizing I forgot to open the valve back up. It was the inlet side. Now the pump is very loud. Is it ruined? It's an Intex Krystal Klear and it was purchased in 2012.
