Faulty Drain Valve....I Think?

Hi,

I hope this question isn't too stupid but am i correct that the water drain valve in my Honwave 4m is one way and therefore i do not close it (fit cover) when i am out on the water?

I tried this but it seemed to let in more water and slightly puzzles me why have a one way valve in the first place.

Maybe it's faulty or me being totally dumb.

As always your advice really appreciated.

Does the Honwave use a one way valve system similar to that of the zodiac SIBs, where a rubber flap for a diaphragm with a central barbed nub that goes through a plastic basket type housing?

If that is the case check for mud or seaweed holding the rubber flap open. Over time those rubber flaps do lose there elasticity and become leaky - they are inexpensive and easy to replace.

My old Achilles had a valve as PT described. It was never one way (though a fair argument could be made for it being one way in the wrong direction.)
ended up keeping it plugged unless I had a need to drain the hull of water, when I would pull the plug and run the boat at a good clip for a while.

The big problem with them is that an inspection and clearing only works until it starts draining, then the crap under the floor blocks it open again (at least it did for me. Should mention that I parked the boat under a large stand of pine and fir trees that were fairly prolific in the dead needle generation department.)

Understanding Plugs & Diaphragm Behaviours

This is not a stupid issue, as many ribbers, including myself, have gone, or are going through this frustrating & unconfortable water issue. In 99.99% of water flowing in cases, is not a matter of changing faulty plugs by a new one, is a matter of getting the correct & quality diaphragm to work on that faulty plug. Here are some examples of plugs & diaphragm behaviours for better tech understanding.

Pic-o1- Comparisson between Asian and Zodiac diaphragms
Pic-02 -Asian diaphragm central pin fit
Pic-03- Zodiac diaphragm central pin fit
Pic-04 -Transom outside plugs & diaphragm comparisson sizes

Have changed all Sea Rider sib water plugs for screw type rib water plugs + zodiac diaphragms, are much better and seals perfect on transom, Final Solution: Go to a Zodiac distributor and buy spare sib diaphragms, change your current sib asian diaph for zodiac ones, will perform excellent. I'm not recommending any particular brand, if in UK can find Avon type that fits asian plugs and seals well, then be my guest. (Consume local products)

If your diaphragm is not sealing correctly and need interior sib water evacuation, open stopper,accelerate engine at a non planing speed to keep sib at 45 angle to evacuate all water, once completely evacuated procede to put stopper back. With a good sealing diaphragm you can have plug stopper off/out at all times.

Happy Sibbing

Well, for what it's worth, my buddies Pro16 (I think it is) has a side-mounted diaphragm (same sort of valve, but not center-pinned. Looking into the valve, it appears to be like a flapper valve.) This thing has never sealed, either.

Thanks for all the advice,

I had a look at the valve and just as locozodiac said, the valve is quite a poor fit. I will try and get hold of a Zodiac one and give that a try.

Thanks again.

I completely dremel out my drain valves. They seem to be far more trouble than they are worth, especially when bits of crabs, fishing line, swivels, seaweed etc. end up below the deck and completely block them up.

New Water Plug

There is a new drain water plug (Bastille Type) on the market, has anybody seen or has one installed on their sib ? Is it a reliable or crappy one ? any comments are welcome. Was offered this new model, but rather stick with proven reliable Rib plugs + Zodiac diaphragms.
