how to connect washer to 3/8 compression water line

[Marcin G.]

How would you connect a washer to the 3/8 compression line ? the washer needs to be installed in the apartment – the only source of water is 3/8 compressin under the sink

I believe washer line is ¾”

now I am looking for some kind of transition to go from ¾ to 3/8 compression.

Would it be better to pick up 3/8 compression to ½ FIP first – standard water line

and then go from ½ FIP to ¾ ? I appreciate any ideas.

You can 'adapt' a 3/8 line to the washer but the machine will fill slowly, causing it to run longer and waste money/energy. Can you tee off 'downstream' of the 3/8 connection to a bigger supply?
