    PMUP for Water Changes

    I have been using a DOS for automatic water changes on my classic. I recently upgraded to a 2016 unit and purchased two PMUPs to do water changes and use the DOS for dosing chemicals again. I already have the 1/4 inch tubing in the walls/ceiling to my saltwater container and the drain I used with the DOS. I would like to use the exisiting tubing for the two PMUPs. Will these pumps work with 1/4 tubing?

    What was the answer? I omly ask as I'm looking to do something similiar. I want to pump water to and from the tank for water changes and like you have ran the 1/4" lines (3 in all) in the walls and also through a flex hose in the attic. My setup is about 16ft high and 80ft run. Ran the first test yesterday with the Apex TopOff pump and it worked. That will be used for the remote ATO from the RODI setup in the garage. Now just need to figure out the In/Out for the other two lines for water changes.

    Thanks for any info.

    You can get a 3/8 to 1/4 adapter from one of the big box home stores. Works great.
