With a flow rate of 10 gpm normally, just how much water is that really? How much water do most fixtures use?
Most homes are plumbed with copper pipe (in larger custom homes might be 1). The maximum safe flow in a copper pipe is 10 GPM (any more flow will produce water hammer). The piping to individual fixtures is usually copper. A toilet will normally use about 2-3gpm, a shower 1 1/2-3gpm, a bathroom or kitchen faucet 2-3gpm, a dishwasher 2-4gpm, a washing machine 3-5gpm. Two people taking a seperate shower in each bathroom at the same time is a good indication of peak use. This represents 6 GPM flow. If you think someone would be using the toilet or using the washing machine, at the same time as the showers are in use, than size your needs accordingly. In reality a 3-4 bedroom 2- bath home will rarely exceed 7 GPM peak flow. In a large home a 10 GPM peak flow might be expected. Its really a matter of money. If you feel you need a bigger unit, we will be happy to sell it. But try to be realistic. Most of the time a smaller unit will work quite satisfactorily.
