For all you wfp users, if you don't carry spare hose to repair burst pipes, for about £2.99 you can carry a roll of Self Amalgamating Tape,
it is 19mm x 10mm x 10mtrs and it bonds to itself, and to irregular surfaces and shapes, and is made to repair pipe's and hoses, For those of you who have satalite dishes, its the same tape that sky use to insulate the plug on your dish, so it is also good for electrical work upto 38kv.
One tip I can give you is when you remove the backing paper, hold it onto the repair, about an inch from the damage, and stretch it, wrap it around tightly for it to bond to itself, and create an excellent repair.
