Hi all just wondering what speed the water should flow out of a cold water tank overflow pipe reason is I installed a new cold water tank to fed a power shower as my other smaller tank wasn’t big enough it now feeds the hot water cylinder, so I made the new tank overflow to test my connections and the water comes out like a slowish running tap whereas the smaller tank comes gushing out like a hose and empty’s the tank till it’s below the dip tube both are connected to the same pipe to the outside just can’t understand why both aren’t the same.
