Waterheater Filter

I was thinking the other day about how a person could filter all the clorine that the city puts into the water to make it "safe"! I already have filters on all the cold water supplies at the sinks and since I have a slab floor there are not options for installing a filter at the supply, so my thought was to install a large filter on the inlet side of the waterheater thus the heated water would be clorine free. Anyone see or hear of this being done without having a flow problem?

Not a good idea.........that and thermal expansion would cause this filter to fail.

Filters at high temperatures will create a situation of bacterial growth in filter.

That is why water softeners are required to be a minimum of 10 feet of piping between softener and water heater with the installation of a check valve.

I do think they make a filter designed for high water temperatures.....but have no idea where you would find it.

hello, you have the right idea. right before the water heater is perfect. however you will have to install automatic WHOLE house
carbon filter to deal with that kind of volume. you could not get away with putting a small cartridge filter in. they are just not designed to handle the volume. whether you get a small 2.5 x 10
or a 4.5 x 10 or even a 4.5 x 20 filter you will be having to change
cartridges too ofter and i think even the largest of these still only has a 3 g.p.m max flow rate. so i would just keep the one(s) you have unless you want to spend more money
