What causes Pentair PRF 1035CS Water Dispenser to backwash at wrong rate?
- EEric AllenAug 17, 2025
If your Pentair Water Dispenser backwashes or rinses at an excessively low or high rate, it may be due to the absence of a drain line flow control. Install a drain line flow control. Alternatively, the drain line may be restricted. Remove any restriction.
