Query: Failed after 6 months

I purchased this product about six months ago. The hand contol will not let the water pressure out of the unit. It was working fine then it just started intermiting, letting water out sometimes, then stopped letting any water out at all. The pump is working but the water stays in the tank. Not very reliable if you can't get more than six months out of a new product.
