divadiow Posted August 7, 2018 Report Share Posted August 7, 2018 I've lost the hexagonal keyed metal water tank plug for our boat. (At the Bath Widcombe Lock Flight water point in the unlikely chance anyone has it!). Are these easily replaceable? How would I know widths, depths and thread pitch of the plug without trying to measure it crudely? It's a 1987 Colecraft. Any pointers well appreciated.

Tony Brooks Posted August 7, 2018 Report Share Posted August 7, 2018 I think any decent chandlers will stock them. Its just the size that may alter but otherwise they seem the same. Link to comment Share on other sites More sharing options...

BEngo Posted August 7, 2018 Report Share Posted August 7, 2018 They are (were at least) a BSP size so you should be able to get a suitable temporary replacement stopper from a plumbers merchant or even a DIY shed. The size is I think 1 inch BSP .Ask for a flanged plug in brass. Repacing the proper stopper will probably involve buying a new filler unit.

David Mack Posted August 7, 2018 Report Share Posted August 7, 2018 Midland Chandler's website shows water fillers with a slot in the top and pump out caps with a hex socket. The hex socket ones are available as a cap only for £4.99 in brass or £5.30 in chrome. For the slotted version you might have to buy the whole fitting. Best to call in with the boat at the next boatyard so you can confirm it fits. Link to comment Share on other sites More sharing options...
Chewbacka Posted August 7, 2018 Report Share Posted August 7, 2018 To reduce dirt and water leaking into the tank you could screw a length of threaded pipe into the hole or even a nipple - just an inch or two - then use a black iron screw cap. Though it’s hard to see in this picture if this would then be a trip hazard or obstruction. I am not recommending you use this supplier, just a picture to show what I mean - https://threadedpipeandfittings.co.uk/1-nominal-bore-black-self-colour-bsp-threaded-unthreaded-pipe-medium-bs-en-10255-pipe-tube/?sku=SKU-B5187EB2&gclid=EAIaIQobChMI_aTbyrba3AIV77ztCh29MAq2EAQYBSABEgJ8RvD_BwE https://threadedpipeandfittings.co.uk/1-jinan-meide-black-malleable-iron-end-cap/ 1 Link to comment Share on other sites More sharing options...

Boater Sam Posted August 7, 2018 Report Share Posted August 7, 2018 You need a glass magnet so it can see it down there. Link to comment Share on other sites More sharing options...
