Wash down hoses

[ashtead]

Saw an interest vid on utube the other day on installing a wash down hose for the anchor. Curious to know if it’s worth doing ? I guess far simply to tee the water off if a bow cabin heads but if you don’t could you run the input from the galley sink I wondered?

Seems a bit wasteful to use potable water. I thought they usually used the stuff the boat is floating in.

Ours Ts off the watermaker saltwater feed pump. No point in using fresh for that. We have a seperate fresh water feed for washing down the boat after a salty sail. It doesn't rain much here so we can't rely on nature

I would have assumed the point would be to use fresh water so that salt was't left on the chain encouraging rust.

Think it’s a trade off between wasting fresh water and at least washing the (salt laden!) mud off the chain/tackle. With sea water you can have the flow/pressure needed for a meaningful wash down without worrying you’ll exhaust potable water in doing so. Probably a good idea to wash the anchor locker out with fresh water regularly, when the opportunity arises, either way.

An effective chain wash hose requires both pressure and volume. Sea water is the only realistic source.

I can see advantage of running from a water maker but I suppose freshwater usage without that means no sea inlet needed and it would operate much like a stern deck shower so volumes not that great . Also the pump might survive better running freshwater? Anyway if of interest do watch Daniel on Polaris vid installing .

Depends on the size of boat, water production and power available.

I dunk the anchor in the oggin if there is any mud on it.

I wonder if the YouTube people spray the anchor with fresh water if it gets splashed by the sea?

T from engine cooling water intakes. Deck hose has its own electric pump. Hose stowed in chain locker. Essential for shifting the grey silty mud that clings to the chain in many sheltered west coast Scottish anchorages as bucket and brush does not work well. Also, useful for final cleaning of anchor after most mud has been poked off with boat hook and washing deck.
Never occurred to me to waste fresh water on this job.

It's not freshwater. its salt water. We just use the same pump that feeds the watermaker as a deckpump. It saves having two pumps

When I asked a local marine electrician to fit a deckwash for me this winter they said I would have to wait a long time and perhaps I could do it myself? I took up the challenge and rather enjoyed it.
If you have a forward heads it is a simple matter to insert a T into the salt water intake. Don’t skimp on hose, use good strengthened stuff so that any bends don’t restrict the internal hose flow.
Initially I tapped the new pump into the same supply as a forward grey water pump. However that simply caused the supply to trip as it was a 10amp circuit.
If you have a bow thruster with a separate power supply then it might help you to cope with the high amperage required by some deckwash pumps. Be sure to insert a suitable fuse if connecting directly to the bow thruster battery / power suppy. I used a 25 amp fuse.
Having cut through the deck remember to stiffen the deck with epoxy in place of foam core if relevant before attaching your through deck fitting.
