Condensate Traps
Product# CT075
Unique ends allow for easy installation without needing to purchase couplings. The transparent plastic material lets the homeowner monitor the water level. Our traps have sufficient height to overcome vacuum created by radon remediation equipment.
A filler cap is included to add water when necessary.
All Radon Supplies condensate traps conform to EPA guidelines (Standard 14.7.2)
Our custom made condensate traps hold more water than conventional traps. Water stays in the trap longer so there is less chance of complete evaporation.
