I want to install ball valve on my raw water hose, in between inner transom plate and water pump. Already have a T in it to plug the garden hose to run engines on trailer, but i want to be able to shut the water and stop it from going out back in the drive. Very easy to find the ball valve locally, but no one can help me having the right size adaptor to be able to connect the hose back on each side of the ball valve! Can i find this easily online?
I didn't find the right solution from the Internet.
