Our water pipe outside the house (that controls the water for the undergound drip lines) must have froze one night and now sprays water :( how do i fix it??

The expansion foam can help, but the issue is the pipes are on an outside wall where they are exposed to the very cold temperatures. When very cold, keep a slow stream of water running at the faucet. Running water doesn't freeze as fast as still water.

Patti, check outside around the outside water spigots. to see in the earth around and near the spigot(s) is overly wet or moist. Someone may have been turning them ON when you weren't at home or a night, as a practical joke. If so, it was a sick one. Also, have your municipality , who provides the water to check "their meter", as something may terribly wrong with it mechanically. Do not accept "No" as an answer. Did you plumber consider a leaking under ground pipe from the meter to your home? Especially, if it is a galvanized pipe, instead of copper or plastic.

Hope this provides more info to consider. Thanks for choosing FixYa.

The reason the water is coming out of the unit and not the drainage pipe outside is for a few possible reasons.
1 -the drain pipe is clogged / plugged (due to calcium build up,or frozen)
2- the line is kinked or blocked.
check the drain pipe carefully, there may be obstuctions.

Clogged drain condensation drain pipe. They use to recommend white vinegar for cleaning, but they now say even it can damage lines for being to strong. The sell a product Zest at home depot, it's like orange and environmentally safe made with oranges or something.

Anyways use that stuff.
I would first check the outside pipe for an obvious blockage like grass, dirt or dead animal. Then right by your indoor unit will be the start of the same pipe, if the leaking is there, then that's it, if it's somewhere else could be in the unit which you will need a repair man, nothing easy inside the main unit except lots of shocking things.

Open the pipe inside and try pooring some cleaner in , wait a bit then turn back on and see. If it's a bad clog, what I did was to take a long hose, run it in the house to the pipe. I put folds in the hose to do it alone, or have someone outside to yell to turn it on. Put the hose against the pipe inside flush as possible and that should force almost anything out. Be sure to have a couple towels ready cause it's nearly impossible to not spill some water doing it this way.

You need to get the blower motor going, the unit is froze up. Try switching the fan spped wires on the control board on the unit in the attic.

If that does not work, replace the motor

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.

your water pipes to and from tank are froze. need heat tape to wrap water lines to thaw lines.

sounds like the overflow drain is picking up the water that means the main drain is clogged.you need to find the main drain pipe if lookin at the air handler in attic there should be 2 drains from unit one higher than other follow it and blow out drain they put the other overflow drain out the eve so if it stars leaking someone notices it and it doesnt damage cieling but it sound like it needs imediate attention befor it does go to the overflow pan and damage your cieling. i hope this helps and good luck

What type of pipe are you looking at?If it is copper then you can fine someone to solder it.If it is plastic pipe with glue joints,then you get some glue call rain and shine,clean first then apply wait a few minutes.But turn the water first.

insulate pipe with rubertex from a/c supply house or hardware
