A(storage(tank’s(tank(can(act(as(a(
settling(basin(for(solids(suspended(
in(the(water.((It(is(therefore(not(
uncommon(for(hard(water(deposits(to(

is(suggested(that(a(few(quarts(of(water(
be(drained(from(the(storage(tank’s(tank(
every(month(to(clean(the(tank(of(these(
deposits.
Rapid(closing(of(faucets(or(solenoid(
valves(in(automatic(water(using(
