  • Q:
    I currently have a 3/4 inch check valve inside a 1 inch pipe, will this valve work or should I order the larger (1 inch) valve?
    A:
    If the 3/4" worked then yes you can use this as the diameter of this valve is 3/4".
    Q:
    Current hose is 3/4" clamped to current check valve. Will this hose clamp to this valve or do I need a smaller size c.v. that this hose will fit on to with clamp?
    A:
    The pipe diameter is 3/4" so you will need something larger hose size to install on the 3/4". 3/4" is the smallest Whale has. If you have further questions contact us at the number at the top of the page.
    Q:
    Can I use this valve in a 1.5 inch Schedule 40 DWV line?
    A:
    Yes, you should be able to use it for that application. This is an aftermarket, universal part that will fit mainly by style and measurements.
    Q:
    Does there need to be pressurized water to make the one way function to work. I have a floor drain that drains into an outbord motor well and occasionally larger waves will enter the motor well and force water back into the boat. I am looking for something that prevents the back flow of this water.?
    A:
    No, this is just a check valve and does not need pressure for the one way function to work.
