Bit of an oddball request really but I have a 1000 litre container in my garage holding 700 litres of seawater for keeping live sandeels in for live bait!
At the outlet tap their is a thread , apx 2" ish from memory and I believe they are fairly standard, I have a very slow leak from the tap and a cap would just put my mind at rest ! The farmer that gave me the container didn't keep the cap and neither did any other farmers that I asked.
Does anyone have one they could send me ? I would obviously reimburse postage and chuck a few quid to Help for Heroes or RNLI
