Chilled Water Flushing Certificate Missing Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the chilled water flushing certificate, chilled-water cleaning record, or flushing signoff is still missing. This page is for HVAC or process-cooling projects where the blocker is the documented cleaning and flushing of the chilled water circuit, not general balancing or commissioning. The commercial problem is that the plant may already be running, but the payer is still withholding the final balance until the flushing certificate is accepted. Your email should ask whether the chilled water flushing certificate is the only remaining blocker, whether flushing has already been completed, what loop, sample, or cleanliness requirement remains unresolved, and whether payment will be released once the certificate is approved. The goal is to reduce the delay to one exact system-cleanliness deliverable instead of broad comments about incomplete mechanical closeout.
