What are the two water plugs for - Danby DPAC8020 Air Conditioner

All boats (except ProStar) have two drain plugs, which allow water to be drained from the boat when the boat is OUT of the water. There is a center T-handle drain (the only one for a ProStar) and a transom drain plug. The lower plug is located in the center of the transom at the lowest point. It will be under water when the boat is in the water.

There may be a water flow regulator at the inlet to the fill valve, which is meant to prevent water hammer or resonance. It is a rubber plug with spiral ridges. Turn off the water supply to the toilet, flush the toilet and remove as much water as possible from the tank. Remove the water supply line at the outside bottom of the tank. Use needle nosed pliers to pull out the regulator plug from inside the valve. Reconnect the water supply line and turn on the water supply. If you experience water hammer or resonance you can replace the regulator plug with a new one that may be less swollen with age. The plug is not needed otherwise and your toilet will fill much faster.

is the water off perhaps.Fact the solonoid hums sounds like it.

There should be plugs underneath the camper to drain the water tanks. Remove them and let the water drain. There should also be a plug on the water heater, remove and let water drain. There is also a bypass valve on the water heater to divert water away from the heater, turn this to bypass. After the water has drained replace the plugs except the water heater plug. The heater plug can stay out. Fill fresh water tank with RV antifreeze, usually about 3 gallons or maybe a little more for larger RVs. Run pump opening faucets one by one till water is forced out and the antifreeze flows including toilet. When antifreeze is flowing out the faucets close faucets and shut off pump. When pump is shut off open faucets, the antifreeze may get slushy in very cold conditions but wont freeze and a little may drip out of the faucets. The water heater may still have a small amount of water in it but shouldn't be a problem if you leave the plug out. Make sure the blackwater and greywater tanks are empty, you can dump a little antifreeze down the drains and toilet to make sure the sink traps are free from water and the blackwater tank has antifreeze in it. Other than that just shut the propane tanks off and youre done. Try to leave a couple of windows cracked slightly to promote airflow and reduce condensation inside the camper

Must be filled with water or elements burn out

If water heater is plugged in and outlet has power... then water should be hot.
If no water inside tank, and tank is plugged in, and outlet has power, then element is burned out.

It may be a leaking frost plug. Some engine blocks have holes needed for the casting of the block or for machining. These are then plugged with cup shaped plugs called frost plugs . These can sometimes corrode and start leaking. Check to see if this is the case and replace plugs if needed. Hope this helps

Sounds familiar. If the engine oil is too full, oil will splash into the spark plug openings. Then, condensation will sit on the oil shorting the plugs. Be sure not to overfill. Also, the valve cover gasket has an inside seal. Once again, oil will partly fill the spark plug hole if the gasket is bad. There is a large hole in back of the valve cover leading right to the plugs. Be careful not to rinse the engine. Gaskets seal the plugs but water can sit on the plug openings.

Yes. Most all water cooled engines used in automobiles willutilize freeze plugs in their respective design. The freeze plug is there to act as a weak point should the water located in the water jacket of the head freeze and expand. Without the freeze plug, the metal of the head would crack when the water freezes and expands.

plugs out and crank the water out , put your finger over plug holes as you do this and will help purge water from crank ! Plug caps away from plug holes !! have a battery jump pack ready as will take a while ! if plugs ok then clean with carb/brake cleaner once most water is out then put a sqwert of fuel in each cyl then plugs in hand tight and get cracking coz if left too long crank etc already rusting ! DONT STOP till you got it running as you will have to clean the plugs several times ! Try all three plugs at first then if struggling two plugs and one out with rag over hole and plug cap away safe from plug hole so not to spark fuel !!!! NO SMOKING !!! Fire extinguisher handy !!! once running ON ALL THREE CYL'S , not one or two as you can sieze the engine take to lake and give a good run and making sure all cyls working ! can do this while strapped to trailer in water as long water circulating !

Plugged holes in spray bar or plugged filter in bottom, preventing water from draining down to the pump area. If the pump can't get water, it won't pump water up into spray bars. If spray bar holes are plugged, water can't get out.
