If i want to blast cold mains back up the hot tap whats the best thing to use to connect the cold tap to the hot tap? Thanks in advance
 
easiest way is to connect hot to cold on washing machine connections, turn on hot then cold for about twenty seconds should do it.
 
you connect the two feeds for the washing machine together at the valves under the sink or where ever they are, using a spare w/m hose or one off the w/m. turn the hot on first then the cold. blast for about twenty seconds then turn off.
 
still the hot water on bath isnt nearly as powerful as the cold. have checked all valves, blasted mains through and still its pony!!!
