Problem: The PRC recovers only water.
Solutions:
1. The PRC is set too low in the well restricting the travel of the intake assembly.
2. Drain the collection canister completely, allow the screen intake to dry, re-prime
the screen, and then reset the PRC so that the water level fluctuation is within
the travel range of the intake assembly.
Problem: The water level has risen past the top of the travel range of the intake
assembly.
Solution:
Drain the collection canister completely, allow the screen intake to dry, re-prime the
screen, and then reset the PRC so that the water level fluctuation is within the travel range
of the intake assembly.
Problem: The drain valve is not fully closed.
Solution:
Empty the collection canister (as described in
Section 2: System Installation and
Operation ), and then close the drain valve by pushing up on the outer sleeve of the drain
valve until it stops.
Problem: There is a mechanical malfunction or a leak has developed.
Solution:
Call Geotech Environmental Equipment Inc. at 1-800-833-7958 for assistance.
Problem: The skimmer intake is not recovering product.
Solutions:
1. There is no product to recover.
2. Check, and periodically monitor, the product layer thickness.
If the water level has risen above the travel range of the intake
assembly at any time between site visits, the skimmer
assembly and collection canister will fill up with water and
displace any collected product. It will remain this way until
reset, even if the water level falls back within the travel range of
the intake assembly.
