HWH fluid reservoir cap broke off

Go to Lowes/Home Depot. Go to the lawn irrigation dept. Ask for a easy out plug wrench. They are less than $10. Once you see it and use it, you will wonder how you ever got along without it. Stuff a paper towel to block off the hole. The paper will allow it to vent and there is NO force that will blow fluid out of the reservoir cap area. Doug
