You probably enjoy an issue with sediment buildup.
You can try first performance and closing the drain valve several times to go and get it to reseal. Make sure you attach a hose to the drain valve to direct the marine.
If this doesn't work, you will need to drain the space heater and replace the drain valve. You can purchase a bright drain valve for roughly speaking $10.00.
Table-top insert repair?
Answers:    If the water is coming from the outlet of the drain spigot, you can buy a hose-thread cap within either brass or plastic and near a hose washer, just screw it onto the shutting down of the valve. This will amass you the time and expense of shutting down the heater, draining adjectives that hot water, replacing the valve- hopefully it would come out, and refill and reheating the water.
