Onboard Sink

[sailguy40]

Maybe someone can give some pointers here. I want to get the small sink on my boat working, Nothing has been modified and it is the original sink onboard the Oday 22's from what I seen. First I have the onboard water tank and a hose runs from that to the sink. It all appears to be intact. Basically, my main question is, how do these little sinks on these boats work? Is there an electric water pump or does it sippon through the hose some way? Reason I ask is because I have not seen a pump anywhere. It may come in handy to have it working if I want to wash a few dishes, my hands, brush my teeth or anything else I may need if for.

You can have a pressurized fresh water system, in which case there will be an electric pump that maintains the pressure from the water tank to the faucet. On our galley sink, we have an additional faucet that is fed by a foot pump in case there is something wrong with the pressurized system. This could be the primary means of providing water to the faucet, in which case it is not a pressurized system. I've seen manual pumps at the faucet itself. I've never seen a faucet fed by siphon, though.

Tell us more.

My experience has been on the O'Days there is a manual pump next to the sink. I had to replace both of mine (head and galley) as they were worn out after 25 years. Is there a pump next to your sink? Or a hole in the countertop where a pump used to be?

Most likely a hand or foot pump kind of thing. I can definitely recommend from experience to make the change to an electric pump as it's very difficult to do anything with just one hand (being that one hand has to always pump). Although if it's a foot pump then that's great. For such a small boat I don't think it would be worth it to install a pressurized system.

Anyways, it's all very simple, there is usually a water tank or bladder to hold the water, an electric pump with a switch at the faucet or a hand or foot pump and of course the faucet itself. Buying a faucet with a switch in it isn't much, pumps are cheap too I think, then you just have to plumb it and hook up the electricity. Good project I think.

Easiest and cheapest install would be a hand pump like a Whale or Fynspray. Especially since the tank and hose are already there. Not really worth putting in an electrical pump system and if I remember the ODay 22 interior, a foot pump would be awkward.

Hi guys, thanks for the advice. Here is a quick video clip of my Oday 22 interior. You can see the sink there. I looked today and I did not see anything electrical nor did I see a foot pump. I am thinking it has to be all manual. Is that lever on the faucet a manual hand pump? If so, I may just need to fill my tank up completely with water and can get it working. I think I am thinking to complex here, I was looking for electric pump system or something. Thought I would here something if I turned the faucet on but nothing. I was just not aware how it works, none of my powerboats ever had a sink since none of them even had a cabin.

Yup, it's a manual water pump.

Well, that confirms I am probably good to go then, just need to fill the tank up with water. Thanks for verifying this.

you may need to 'prime' the pump first. At least to get pressure into the line. Sometimes the handpumps to wear out and become useless and require replacement.

On my previous boat the tank was higher than the sink so it ran by itself, but I put in a bigger tank low down, and a foot pump. I really like those foot pumps, wouldn't want to pump a lot of water with a hand pump.
