metal vs. plastic

[danny zubot]

The output from the skimmer is 1.5 inches but I think I'd like to reduce the size to 1.25 inches to save money. Will that work or will that retrict the flow too much? The skimmer uses a Mag 18 which has a 3/4 output, and the injector reduces that to a 1/2 inch. Chin Lee says that I should stick with 3/4 inch hose right up to the injector, but I was thinking of changing the injector input to 3/4 inch. Any advise would be welcome as this is my first becket skimmer.

Thanks for the info about retailers. I was at Rona last night and found that some very key parts were not available. I'll check out bothe places.
