hi, you seem to know a lot. so i went by at lowe's today to check for fittings for my mag7 return pump. it has a 1/2" male thread outlet. And my bulkhead is 3/4" barb. I want to use 3/4" vinyl tubing to connect my mag7 to my 3/4" barb, but the outlet is only 1/2" on my mag 7. I tried to look for adapters and fittings to try to get my 1/2" male to a 3/4" hose barb. any ideas? and where i can find?
