Thank you. I will buy a large bottle of water and get it blessed. Then maybe a nice sprinkler type bottle later on.
Excellent idea. I suggest you make arrangements with the priest ahead of time. Take a half an ounce of salt with you as he will exorcise and bless it before he adds it to the water.
Every year we buy three, one gallon bottles of spring water and the priest is very happy to bless the salt and water. We use spring water as it's gone through God's filtration system not distilled nor RO that removes minerals, nor the local water purification system that adds chlorine, flouride etc.
With five fonts in our house and a bottle in the car for emergencies and the cemetery, three gallons last about a year with the dehydration from heating and air conditioning.
I suggest you put natural sea sponges in your fonts to slow down dehydration.
Father once commented that he wished more people got large quantities blessed as he's forever having to fill up the tank at church.
