Rittenhouse Hypro 9910-D30 Diaphragm Pump Repair PT1 

Long shot you'll see this, but I'm having issues with the sight glass "melting" so to speak. It softens to the point it starts leaking. I've replaced it 3 times, twice under warranty, once I purchased it. Kurt I believe that builds the sprayer said he had never seen it do that in his 15 or so years of building and selling them. I removed it, replaced it with a gasket and a 1/4" piece of plexiglass. Well 2 weeks later, the plexiglass has cracked down the middle enough to where it's leaking again. Have you heard of this before? I do have a diaphragm rupture, happened 2 days ago, 2 or so weeks after I deleted the site glass. I'm replacing the diaphragms soon as the parts arrive in a couple days.
