I was sold a liquid separator/water trap as a part of my new priming system to protect the system against flooding. However, I regularly loose prime to my pumps and my system still floods.

Liquid separators, also commonly referred to as water traps are frequently employed improperly to protect the vacuum pumps from flooding in a poorly designed priming system. With their typically small capacity they rapidly accumulate normal condensation. If unchecked they isolate the priming system, and the prime is lost. A properly designed automatic priming system fully protects critical components against flooding. LYNN’s system designs incorporate protection from flooding and carryover. The use of external separators is actually more of a nuisance than an asset.
