Does this unit need water?

I am re plumbing a house that has had most of the copper water pipe stolen. There is an a/c unit that has a 3/4" copper pipe coming out of it and I don't know if I need to tie this in to the water system. The unit is a Rheem AU-42B10.

I am making a plumbing repair to copper pipe. There is a small trickle of water that I cannot stop flowing. What is a good way to block the water to make a good joint?

Jamb a piece of white bread(wadded into a tight ball)into the pipe. Work fast. Bread will stop flow for a bit, but will breakdown quickly under pressure and dissolve with no blockage.

The Leak - How to Repair the Leaking Water Pipe

Let's see how easy it is to fix that dripping and give you peace of mind. With some of the fantastic improvements in plumbing fittings in the last few years, plumbing repair has been made very simple. Many leaks are caused by just a couple of things. The pin hole in the copper pipe that is caused by pitting inside the pipe. Usually this is caused by poor water quality. The inside of the pipe flakes off to cause a hole inside the pipe that eventually gets through to the outside. These often are given away by the green spot that usually is seen on the outside of the copper pipe first. This is caused by mineral left by the water evaporating off of the surface of the pipe. So in all reality there is a leak before there is a leak. The other main problem is the joining of two dissimilar types of pipes. Copper and PVC or Copper and Pex are two examples. The expansion rate of the two different types of materials is very different. This causes friction and constant movement where the two meet. This movement eventually will cause enough of a gap to allow the water to leak out.
Until recently there where many redneck fixes out there most involving garden hoses, inner tubes, hose clamps, epoxy, and many other creative fixes. I have seen way too many to describe all of them. Now there is a great way to fix those leaks with a simple push fitting. The new design of the push fitting allows for the pipe to be cut at the hole and then a coupling just pushed onto the pipe to fix the leak. The hardest part of the whole process is to get the pipe cut neatly. The same fitting can also be used to replace those pesky plastic to copper unions that always seem to give trouble. Joining different types of piping is no longer a problem.
By doing a quick search for push fitting you can find a number of different suppliers of this type of fitting. I have used a number of different ones and they all seem to work well. My preference is the brass types as they seem to be much more rugged in construction. The price of those fittings also reflects that. The most common that I have seen and used are the Sharkbite Brand. These are very good, are sold in many plumbing supply houses, and in Home Depot Stores. Other companies include Watts, Probite, Tectite, and Speedfit. I'm sure that I have left some out. These are some that I am familiar with and have used.
Bottom line is that it is now very easy for even a desk jockey to fix his own pipes. Go by the closet home improvement store on your way home. Pick up some of these fittings and impress the wife with talents that she did not know you had. You may even get brave and do that small plumbing project that she has been begging for. Now you can use these fittings to cut into that water line to run that new outside faucet or hookup that water filter yourself. With the push type fitting plumbing has been made easy enough for anyone to be able to do it.

How can I repair water leak?

Good grief, what kind of water leak? In your car radiator? In the house from a copper pipe? Or a toilet, a sink, a faucet? All these leaks require different fixes. Let us know where the leak is from. Then we'll have a better chance of giving you the correct advice.

I will tell you this, if the leak is from a "pin hole" in a copper pipe in your house you need to get a water testing kit to see if you have acidic water eating away your copper pipes. If so you need to replace the copper pipe and then get an acid neutralizer ASAP. If you do not get an acid neutralizer all of your copper pipes will be leaking since the acidic water has been eating away at all your pipes.

Searching for black water release on 2013 cougar 27rks

That should be easy to locate. Outside, down low. Usually black, 3" diameter. Has a cap over it (or should). The unit will have 2 pipes running into it. One usually 1 1/2" or 2" for the grey water and a bigger 3" for black water. Made out of PVC plumbing pipe, just like in a house.

Water from bathtub faucet is orange when first turns on. The plumber says it is not rust. The pipes are all copper. It becomes clear after about 30 seconds but by the next morning the water is cloudy...

You didn't mention the source of the water. Is this a well or connected to a water system? If is a well you might need to install a filter on the line coming into the house. Does the orange water stain or have any odor? It is possible that there is a loose connection somewhere allowing sediment to leach into the line when there is no active flow.

Water is leaking from the cold water pipe on the top of the water heater. Is the whole thing broke?

Without seeing how the plumbing to your heater is piped, its hard to say.I would venture to say that the heater is ok, unless its very old, and you just have to repair the leaking pipe. If its plumbed in Copper, and you are not familiar with sweating a joint, then you may need a plumber, however if its Galvanized (iron), CPVC or Poly you could do it yourself. If you could e-mail me a picture or two, I could tell you exactly what to do. If its leaking bad, you need to shut the power off and turn the water off to the heater, should be a valve located in the cold water line near the heater, which will turn water off to heater but leave it on in the rest of the house.

Water through the door has an after taste. We recently had copper plumbing installed, and since then we have gone through three filters, disconnected the water line and flushed 10 gallons of water through...

Sorry to read about your problem, I hope this helps you out.

you must have a large amount of solder resin in your line, thats from putting the joints together on your copper pipe...should have put pex pipe in...may have to run a resin cleaner thru the lines

I tried to help you. Please help me and Rate/Vote on my response, thanks and good luck

Removing a built in Asea Skandia cylinda 1200

Its normal to have the water supply from under sink to dishwasher 3/8 soft copper. If there is a water stop under sink for dishwasher go ahead and shut it off. If not you will have to shut water off at main. Now you can unscrew supply at dishwasher, it's close to the front on left side. Its a 3/8 compression nut, you can use a small cresent wrench.

Broken copper pipe that suplpy water to the ice maker machine

Assuming that this is the external connection from the house plumbing to the machine...

The pipe will have to be cut cleanly with a tubing cutter and the ferrule and nut will have to be replaced with new ones. There should be a brass nut attached to the water valve where the water line normally connects. Unscrew this nut and take it to Home Depot (or local plumber) , they will have all the necessary parts for you, including the tubing cutter.
