My old boss taught me to dry-fit everything first, that saved my shower pan last year.

Three years on the cheap feed?

Actually, the key is matching the flow to the particle size. Too fast with silt and you just create a vacuum seal on the screen, that's what causes the instant clog. Slowing it down lets the slurry form properly and carry the material through. It's totally worth a test run to see the difference.

That patch test only checks for allergies, not for how someone's skin barrier will handle the full treatment. A reaction like that is a service issue, not a product issue. You should cover the cost of fixing it until her skin is back to baseline, because the problem started under your care. Eating the cost on this one is just part of doing business right, even if it stings your wallet a little.
