Thru Hull Connections For Water

OK: I am wondering, folks have told me about the use of raw water intake for cleaning purposes, i.e. washing dishes, washing down anchors and rode, washing down decking. So, where does this water come from? The boat is relatively new, yet these accomodations have not been met or fullfilled at this time. Do new thru hull connections with valves get established or do manifold systems come into play with existing water supply systems, such as engine cooling supply? If I take water that is dedicated for engine coolant purposes, and use them for other things, am I going to effect the design intent of the manufacturer?, Or what or wherever else? What about A/C Systems? We are talking about any water conditions to satisfy the supply requirement, i.e. again, fresh, brackish, salt water, ocean, where ever? How can those of us that cruise, economize the use of our fresh water supplies and satisfy general wash down or other cooling requirements? IF, I need an additional thru hull connections, how do I do them? How do I know that I need them? It is a hole, yet, boy do I hate like hell to put a hole in my hull. I would consider that others here may wonder the same thing?

Thru hulls

are all typically seperate, ie one for the head flush (intake), one for the engine cooling (intake), one for the sink discharge, one for the head discharge (Y value in off coast waters!). There are others, but they are above the water line. I guess if you wanted to wash down your boat with salt water (assuming your are salt water sailing), you would put a new one in. I don't think I would wash my dishes in any coastal water...either salt or fresh....whats the point in washing if you are going to rinse with ocean/lake water? I guess though, you could tap off the toilet flushing thru hull as this is not being used that often and neither is the wash down or dish washing....... Thru hull fittings are relatively easy to install, if you have the right tools ie drill bits etc. I am sure there are a ton of techical instructions on-line for this. Greg

another hole in the boat

I would not tap into the the engine raw water intake, BUT, do you have a salt water galley pump? Since I doubt you'll have some one doing a salt rinse of dishes as you are pulling up your anchor and want to wash it down at the same time.....consider existing thr-hulls which would not be used st the same time as you want to use the wash down. Most would have engine running while pulling up the anchor-do not want to create a competeing environment..good luck.

t off head intake for raw water washdown; a/c has dedicated intake with a t off that for a salt water spigot at the galley. good for rinsing, cleaning dishes and dirty stuff with a final fresh water rinse.

manifolds

Manifolds are best reserved for combining several low-pressure discharges lines into a single through-hull . I don’t recommend them for intakes.

Head intake line for washdown pump

Tap into the head intake line for your washdown pump. Just put a T in after the thru hull valve and take the water from that line to your washdown pump. It is where mine is taken from. I have two wash down points and hoses - an anchor well wash down point and one on the stern I use to rinse out the cockpit. We are on Kentucky lake, so we don't have to deal with salt. Works very well.
