Query: poor quality pump

This is the beginning or the second or third season I have had this sprayer. The backpack part is ok, the shoulder straps are reasonable, but it really could use a hip belt - I added one. When the pump works, its a good sprayer. But the pump has been poor quality from the beginning. First, after a lot playing around with it, I finally found a piece of plastic debris from the fabrication process inside the pump causing it to work intermittently. Notwithstanding that, the pump seals are very poor quality and do not seal well, leaving me again with no pressure. I am a a real do-it-yourselfer and fix all kinds of stuff. But this pump is such low quality that I am not going to bother getting replacement seals, which would be a trivial repair task. Rather, I am going to throw the whole thing away and buy a different brand.
