Check valve position

hrlevyhrlevy Member Posts: 18
I am installing a laundry tub pump for washing machine to drain into. I was wondering if the check valve can be installed horizontally or does it need to put vertically. All the instructions say is to install near to pump.

thank you.

    but if you can't do that

    a regular swing check should -- in my view -- always be installed so that the flow through it is horizontal or upwards -- never downwards.
