How is it loud? What type of PVC are you using? (sorry, haven't read the whole thread, maybe you already said). The reason I ask is because, some people use spa flex PVC to connect their return/closed-loop pumps so that it absorbs some of the rattle or chatter. Additionally, maybe you could put the pump on some neoprene or something to absorb the noise? Line the stand with something (carpet? too ghetto?) to absorb more noise?
