anti-siphon valve drain

[PabloPicasso]

I have an in-board volvo 2001 and the output from the anti-siphon valve currently drains into the bilge under the engine. I have never been happy with this arrangement on a number of counts: *I don't like water dripping inside the boat, **I can't see if it is dripping water and indicating it is working (rather like a telltail on an ouitboard, no good if I can't see it)

So I was considering re-routing it so it drains through a bulkhead fitting (I'd have to fit one especially). It would then drible outside into the cockpit drain where I can see it, and keep the bilge dry. Apart from it occassionally wetting the cockpit floor, is there any reason why I shouldn't do this?

mine piddles into the cockpit so i can see what is or isnt happening

I would say that would be a very prudent idea indeed! I sailed a boat with a "Welly-Washer": a little fitting in the face of the helm seat that squirted skin temperature water into one's seaboot, but otherwise let one know how the engine was faring...

mine comes from between the raw water pump & HE so its cold (in UK waters ) & straight above the drain. last week for the very first i detected a different note, we had weed partially blocked filter. it took the dinghy pump to clear it, prodding failed.

Good idea

You could then remove the valve it it so that it pees all the time like an outboard engine tell tale. Probably also restrict the diameter at the end so that you dont pump too much cooling water down the drain.

i made my own & restricted ir with a small hose clip ( sorry about the caplock)

You need to check which sort of valve it is. There are two types, one with a little disc that closes when the engine is running and opens when it stops. If it is kept clean it should not drip from the hose. If it is dripping that indicates it needs cleaning. You can remove the disc and route it overboard, but there is a valve designed for this with a smaller outlet.

Yes mine has a little rubber/plastic diaphragm just a few mm in diameter inside. I think it's meant to dribble all the time

Mine was originally the type with the valve in and it vented into the cockpit locker (not ideal and couldn't see if it was leaking!). I removed the valve from it and routed it to the transom where I could see it when standing at the helm. Vetus spares sold me the correct miniature skin fitting for a couple of pounds that restricted the flow to produce a reasonable jet that is easy to see.

That's what I did with mine, removed the valve and routed it to the transom so should get a 'piddle' when the engine is running - must remember to check when I go down to the boat next.
