Not quite sure why you bought a dishwasher Shelley, that's a woman's job. If it wasn't for Pankhurst and friends, you would have a mangle and dollypeg also. Just get back in the kitchen and get the fairy liquid out. Remember "For hands that do dishes can be as soft as your face, with mild green, FAIRY LIQUID"
Damn, I'm hungry now, can i have a sammich??
On a serious note. You can buy these "self tapping washing machine taps". Just pop to your local DIY shed, pesay B&Q, Homebase and ask for these washing machine taps. You just need a screwdriver and presto, as many hot and cold taps as you need.
Make sure you keep a bucket under for a few hours testing, you may need to tighten the screws or turn the tap around itself more to make a seal. These sell for about £6 each, and if it fails, calling a plumber will replace then piece of pipe damaged and you have also lost the price of self tapping taps.
Kind Regards, Dan.
