Coddy Posted February 22, 2015 Report Share Posted February 22, 2015 Did anyone else watch Dragons Den tonight A chap and his son have come up with a way of changing sea cocks without having the boat out of the water. Looks a good idea, however if you have a grill on the outside it won't work, another idea for it's use would be is to stop water coming up through the exhaust outlet should you need it. Downside is the cost, the mark up is high but then again it is in the marine world!!!! Quote Link to comment Share on other sites More sharing options...
Bramble banker Posted February 23, 2015 Report Share Posted February 23, 2015 I did, and agree expensive for what is not new technology, I saw one of these being used on papas boat years ago and we in the plumbing trade use something similar that would also work just as well. http://www.corgi-direct.com/jet-swet-water-flow-prevention-12-3420428 Neither would stop you getting wet but as a product ....

Kingfisher 126 Posted February 23, 2015 Report Share Posted February 23, 2015 Just imagine the water pressure if you took a pipe off an 1" inlet while you tried to get the stopper in, one serious jet of water and if you dropped it etc a serious problem. A great idea as an emergency but I would never try to use it as they said!! Playing with sea cocks is a job for out of the water, always tight and awkward and if the seal is broken onto the skin fitting and hull more problems.

Jim Posted February 23, 2015 Report Share Posted February 23, 2015 Yes I saw it and I thought . . . . Very good idea. Then I thought . . . . BIG mark up ! but as Dave said . . It is the Marine Industry. Then I thought . . . . those sea cocks begin to weep for a long time before they completely fail and most boats are lifted out, cleaned and anti fouled quite often. That's probably the best time to change them. Yes you could keep a set on board, but do you keep a set of spare sea cocks on board ? Always good to have spares but where do you draw the line ?

Brian Posted February 23, 2015 Report Share Posted February 23, 2015 Looks a bit risky to me, you've got to remove the pipe, then open the sea cock to insert the bung. Then you have to remove the sea cock and fit a new one, probably one handed while holding the bung in place. Kingfisher 126 1 Quote Link to comment Share on other sites More sharing options...

Coddy Posted February 24, 2015 Author Report Share Posted February 24, 2015 Don't forget there big pitch to get a Dragon was to make it a compulsory safety item, I don't see that happening as in the UK they wont make life-jacket wearing compulsory to I see little chance of that, however pigs DO fly so I am told and that will be a nice earner for someone if it was.
