Water leaks in the house from under the unit.There is a drain pipe that leads to the outside but we dont know if that pipe gets clogged or needs service.

All A/C units drain water and need a clear path to drain water. If window unit the unit MUST lean to the outside so the condensation water can drain that direction and insure the drain hole is clear of debree. If an indoor central a/c unit the drain must be clogged the unit is leaning away from drain or the pipe going to the drain is clogged somewhere as it exits house. Cant drain if doesn't have a clear path to do it's job. Doubt it's a problem with the brand.
Show Less I hope this info helps Russell.

What is leaking? If it is water, you need to find the drain pipe leading from the inside unit to the outside of the house, and open up the obstruction in it. You could push a wire up through it, or send some compressed air up it. The drain pipe is probably near the ground next to the foundation or in the ceiling of an outside porch.
If this is a window unit leaking water you need to clean the obstruction out of the drain pipe or hole on the outside of the window, probably at the bottom outside rear of the unit.
I wasn't sure from your question if it is leaking water, or leaking refrigerant gas. If it's the gas you probably need to call an A/C repair service.
good luck,

It sounds like two problems.
Problem 1) Clog inside faucet or clog inside pipes at faucet
Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
My bet is clog inside faucet.

If you have galvanized pipe that meets copper pipe, this can be trouble spot.

Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

If cold water shut-off is leaking, then replace shut off.

If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

If TP valve is leaking, then replace with same temperature and pressure rating. New TP valve threads need teflon tape to seal pipe.

Problem 3) If pressure is low all over house:
Buy pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

Test pressure on water heater drain valve.
This says if pressure problem is before -or- after water heater.

If problem is before the water heater, then shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.
Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
Read articles above about clogs inside water lines.

Water should come out of the back of a wind unit when it is humid out, usually a drain hole. If water is leaking inside from a window unit, check that the outside drail hole is not clogged or maybe it is not tilted downward enough outside (Usually a very slight tilt down toward the outside to help the water drasin out the back outside). Also, if you have excess water forming, you may need to clean the coil. For central air units water should be drippng outside the home via a pipe or tubing and if the drain tube or pipe is clogged with scum that forms inside the pipe water will back up and overflow in the house near the heater/air conditioning unit. Also, some units have a pump to pump the water out and it may not be working.

I assume it is dripping water when the AC is running. If you look at the attic unit, there should be a PVC pipe running from the unit - probably an insulated PVC pipe. This pipe probably goes across the attic to the edge of the house and drains outside. The drain pan may also have a drain pipe, but the one on the AC unit is the issue, and is probably plugged. Go outside and see if you can locate the AC drain pipe. See if the ground is wet below the pipe and if water is steadily dripping from the pipe (with AC running). If the pipe and ground are dry, the pipe is plugged. If you have a wet/dry vac, try connecting it to the drain pipe outside to see if you can **** the pluggage out. If you can get it clear, water should start dripping out of the pipe. This same thing happened at our house. I decided to cut the pipe in the attic, and add in a PVC isolation valve, tee, and water hose connection with plug, so I can valve out the AC unit from the pipe, remove hose connection plug, and hook up a water hose and flush the line to outside. Lowe's sells all of the PVC pipe fittings. The water pressure from the hose will always flush out the algae and crud to the outside of the house. I can also remove the plug and pour a cup of bleach down the drain pipe every couple of months to keep algae growth in check. I also cut out the trap (u-leg) from pipe in the attic and purchased a ready made trap a Lowes (the contractor who built our house had made a lousy homemade trap). I purchased a few PVC elbows and installed the trap on the drain pipe outside. By the way, our AC drain pipe comes out of our wall outside and drains near our outside unit. Our secondary drain pan drain pipe comes out outside from an eave on the side of the house. I don't know what you drain line looks like (it may have a port to add bleach, or some cleanout provisions, maybe not). If you choose to modify/improve it, then make a sketch of it, go to Lowe's and get the PVC parts you need + PVC pipe primer and cement. PVC cement dries fast. Remember, the pipe must flow downhill from you AC attic unit. You can use a regular wood saw to cut the pipe. I hope this helps you. You need to keep the drain line clear as algae will continue to grow in it. Pouring bleach in the line every month or two helps. You also need to check maybe once a month that the line is draining properly (check to see if dripping outside). You can get some serious water damage to your ceilings if the water backs up and overflows. I discovered that our drain line was plugged just in time as our drain pan drain line was also partially plugged and drain pan was about to overflow.

When your refer defrosts a couple times a day it produces about a quarter of a cup of water each time.This occurs in the freezer section.The water travels down a drain pipe (or tube) that leads to a drian pan in the bottom of the unit. It is collected and evaporates from the heat of the motor.
If the drain is plugged water will form inside the unit itself.If the drain tube has somehow moved and not allowing the water to collect in the drain pan it will go on the floor.Either way,if the drain is the problem the amount of water should be pretty small, no more than a cup or two.If you have an icemaker or ice and water through the door and the amount of water on the floor is more than a cup or two. I would find the water shutoff for the supply line(probably behind the unit in newer homes)and turn it off.Clean up the water and wait a day.If the water goes away assume that one of the plastic lines in the unit that carries water to the icemaker or door is leaking.If the water continues I would suspect the drain.The only way to check the drain is to unplug the unit and remove the cardboard back,locate the drain pan and see if water is present and that the drain line is in it's proper place.
If one of the water lines is leaking you will most likely need a service tech.
Also it's best to turn the icemaker off by lifting the arm or switch before you turn the water off for testing.

OK lets see what we can help you with here. The condensate drain is clogged. There are a couple of ways to clear this clog so lets give it a try. If you know where the drain for the a/c is located outside (usually by the outside condenser unit) it will be a pipe that is just sticking out of the side of the house, if you find it take a wet/dry vac and place it on this pipe and turn the vacuum on and make a seal with your hand this should unclog the drain. If you don't find this pipe outside the house then go to the furnace and you will see at the bottom of the furnace a pipe (PVC) white, this is the drain for the unit inside. Take the wet/dry vac and have it at the ready in the event the clog is further down the line than at the furnace itself now the fittings on this pipe should not be glued together due to the ability to access for this very purpose. Take the pipe apart at one of the fittings and place the wet/dry vac on the end of the pipe towards the furnace and using your hand make a seal and evacuate the line. Do this to both sides since you don't know where the blockage is. If you are unable to separate the pipe at any fitting you will need to cut the pipe and at the spot of the cut you will need to repair it with a sleeve. Remember that the drain pipe is plastic and is made of pvc so you can get a repair coupling from any home improvement store for this repair.
Hope this helped you some

you have a clogged condesation drain. To fix this you need a shop vac and take it to the outside of the house near the a/c outside there sould be a small white pvc pipe which is your condensate drain. Take the shop vac and put it on this pvc pipe and turn it on. You need to make sure that you get enough suction on this pipe to pull the clog out( most of the time the clog is an algae build up at the bend of the drain line. This should take care of the problem. To maintain the system so it doesn't happen again do this one a year with the shop vac. Also if you want an a/c supply store can sell you tablets that sit in the drain preventing this from happening in the future. Goo luck hope this helped

All A/C units drain water and need a clear path to drain water.
If window unit the unit MUST lean to the outside so the condensation water can drain that direction and insure the drain hole is clear of debree.
If an indoor central a/c unit the drain must be clogged the unit is leaning away from drain or the pipe going to the drain is clogged somewhere as it exits house. Cant drain if doesn't have a clear path to do it's job. Doubt it's a problem with the brand.

Can you get to the hose in the house unit? If so canned air
