What size water softener do you need?

For residential and other drinking water application we usually recommend that a water softener be regenerated about once per week. During regenerations high concentrations of sodium chloride help to sanitize and clean the resin bed. If you have iron in the water, a resin cleaner added to the sodium cloride will aid in reducing fouling and will help the resin last much longer.

With most water softeners you will have a choice of salt setttings. We usually recommend that residential softeners be regenerated at an 8 lb. per ft3 low salt setting. The following information is based on these parameters.

More info about low salt settings.

Here is the specific information about the water softener you need

When we look at the data entered above, we see that your peak flow rate of 7 g.p.m. and your capacity needs of 28000 would both require a water softener of at least 32000 grains. This make things a lot simpler.

Water Softeners are available in the following sizes :
15000, 24000, 32000, 40000, 48000, 64000, 80000 and 110000 rated grain removal capacity.

We have calculated your needs as 28000 grains based on usage and 30000 grains for flow rate. We will make the following calculations and recomendations based on the avalable sizes of 32000 (1.1 Ft3) grains based on usage and 32000 (1.1 Ft3) grains for flow rate.

Considering these facts, the 32000 grain softener we are recommending would regenerate about every 8 days.

If you select a water softener with less then a 30000 grain rated capacity, you could start to experience problems with hardness breakthrough, pressure drop and/or unstable water temperature in the shower.

You can always choose a smaller softener if you can lower your usage. It is amazing how much water simple tasks around the house can take. Click here for a list of ways you can reduce your water from this EPA article.
