Non return scupper plugs

I've seen on the youtubery, that the Old Town Predator PDL comes with scupper plugs that have a non return valve in them, allowing water to go out, but not in.

Does any one have any idea where I could get 3 of these? And if any one has these, what's the diameter of them?

oops, here they are - https://www.austinkayak.com/products/66 ... -Each.html I wonder what shipping to NZ will be....

Or you could go for the more local option...

I put a non-return valve in my scupper, but it rapidly starts leaking as bits of sand or seaweed get in it, and stop the valve flap from sealing.

ahhh, good to know, I ordered a couple from Coro Kayaks, they're 34 mm in diameter which is less than my scuppers, but I'm going to glue them into my existing 'cup' scupper plugs and see how they go.

I don't much launch from sand but I will take care to keep em clean

thanks for that observation.

Having used these myself, I’d recommend that if you’re surf launching, don’t put the non return scupper valves in until after you’ve cleared the surf...

Reason being that if you take water over the front and the cockpit get water in it, the water can’t escape fast enough if The valves are fitted and you loose the ability to paddle and manuouver quickly with the additional weight

I emailed them first, as my yak had bigger scuppers, than the plugs looked to be and they sent me the measurements pronto, delightful!

And I ordered online, fast service and a lovely note from Janet, cheers Janet.

Now, you might ask, why buy scupper plugs that are too thin for the holes?

Herein a pictorial explanation ::

1. this is the plug the 'yak came with

3. ahaa one fits in the other, I was thinking of wrapping tape around the thin one for a snug fit, but it fits in the original one perfectly

The old grey floppy rubber things that came with the Kayak are a #@$%& to use, they fit well enough, but you have to use two fingers to push them down far enough to seat them and that's difficult at the best of times let alone on the water and they can rupture if a rod butt is used...

The new ones sitting inside the old, provide a good 'handle' to push on, making the process simple and easy. And again I can always get out my trusty bicycle repair kit, if I change my mind.

Hands up anyone, who has still got, a bicycle repair kit.

Note, that I didn't post this in "Tips and ideas to Keep It Simple "
