So I'm newer to my 1989 Newport 33 and I've been slowly working my way through the maintenance tasks. Last time I was making a small adjustment to my packing nut I ended up bumping a small ball valve in a hose that was coiled up near my hot water heater. When I later started the engine I noticed that things seemed different and upon inspection my raw water strainer didn't look right. Turns out that this ball valve I accidentally cracked open caused a vacuum leak in my raw water inlet and I was not able to pick up raw water for cooling. Thankfully I noticed things before any issues were permanent. Yes I even popped open the water pump and checked the impeller.
So now in looking at this ball valve. I have a hose that goes from my raw water seacock to my raw water pump. Then from that line I have another hose that is Teed off of that line. It is then run near the hot water heater and coiled up. There is a ball valve in the end and then a few more inches of hose after the ball valve... The end of this hose is then just open. I can't for the life of me think why its there. I've been contemplating replacing the hose between the raw water strainer and the seacock with a straight hose that doesn't have this T connection in it but not knowing why it may be there I hesitate to change things that I don't yet understand. So any help in understanding why this is setup this way would be very much appreciated.
