How do you connect a copper water pipe to a flex pipe?
The quick and easy way is to use a compression "Shark Bite" fitting. It slips onto the copper pipe and creates a tight fit. Then use a threaded or pex flex adapter for your for the connection.
Sweat on a male adapter to the copper pipe then just screw on the flex hose. You can also cut the pipe sweat on a tee then use a nipple and male adapter.
I had a water heater installed and the guy used a galvanized elbow at the top of the heater to connect the copper flex hoses is this proper?
You want to replace old lead pipe connected to cast iron sewer pipe with copper How do you connect the copper pipe to the old lead pipe or to the cast iron pipe?
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting
It is not the type of pipe that is important, it is what you are putting through it. Copper is commonly hooked to black pipe for gas lines. Black pipe for natural gas or propane and galvanized for water. Either can have copper attached to them. Due to the electrolytic decay caused by attaching dissimilar metals, you would need to use a dielectric union to connect galvanized steel to a copper pipe; otherwise the joint…
Is it okay to connect copper pipe to brass to galvanized to brass and back to copper or will it cause a reaction that will corrode the pipes?
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
I WOULD NOT I wouldn't I would use copper strictly The above is clearly opinion and not very helpful if you have existing PVC pipe or have an application which requires it. Try searching on "PVC to copper adapter", you should find many to various adapters and should be able to find one to fit your application.
Wet on the surface is no problem, it will evaporate with the torch. If there is water in the pipe, it will not solder because the water keeps the copper from getting hot enough. As long as the water is below the point of solder, it will work. Open the nearest valve or have some way for the steam to get out of the pipe.
A dehumidifier is a device for the removal of moisture from the air. The copper pipe that is not connected is almost certainly a drain pipe. As the dehumidifier removes moisture from the air, it has to collect and then drain in some way. A drain pipe would handle the latter chore. Consult the manufacturer or a distributor for a manual or just some information.
