We switched to brass quick connects for both the drain and both water line inputs. Works wonderfully. Ordered the quick connects off of amazon as I needed three and one for dual lines. Found all the reducer pieces and parts at Lowes in plumbing under the hose connector section. Could not find them online or at Ace. Our lines are 3/4 and reduced to 1/2. Did have to add a male to male 3/4 adapter from Hose thread to pipe thread. Less than $5 an adapter and well worth the investment. With the weight of the brass on the end the line seems to drain a little faster too when removed.
