Whale Bilge Accessories In-Line Non Return Valves
InLine Non-Return Valve 1" - 1-1/2" - Whale Water Systems
InLine Non-Return Valve 3/4" - Whale Water Systems
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?
If the 3/4" worked then yes you can use this as the diameter of this valve is 3/4".
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?
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.
Can I use this valve in a 1.5 inch Schedule 40 DWV line?
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.
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.?
No, this is just a check valve and does not need pressure for the one way function to work.
