Disconnect each shut off valve then blow through the pipe with a compressor - then drain and clean the tank, this should be done every 4-5 years to avoid this problem.
warm water and soap help pick up all the debris on your hands
They don't purify it. They simply clean out dirt and other debris, very much like a coffee filter. I wouldn't recommend using it to purify water, as it would NOT clean out the microorganisms that can make a body sick.
Air in the pipes from a hole, break or crack somewhere along the line, or from a loose fitting or valve near or at the water heater; possibly caused by a mineral or debris- clogged filter screen at the faucet or discharge end.
Yes it can be buried under ground Type K in most cases for domestic water supply and must be clean fill (sand) no rocks or other debris
on equipment with small engines they are made out of rubber..if its a house hold application such as a stove or a hot water heater they would normally be made out of brass
To get debris out of skimmer lines once the skimmer has been replaced, you need to blast air or water through the lines to push everything out of them. The lines must be disconnected at both ends during this process.
Flush the lines from a clean potable water supply
When you are installing a Reliance water heater, you really need to make sure that there are no leaks in your pipes. These leaks can be rather dangerous because of all of the electrical lines that are around. You need to have these electrical lines so that they can be hooked up to the water heater, so you cannot move them. If they get water on them, though, you could put people in danger of being shocked. It is very important that the area around the water heater is always clean and dry in order to prevent this type of danger.
You don't, you replace them.
Dielectric union
Yes. Allsorts of debris, nests, critters, etc., can accumulate in a pipe before it is installed. If the pipe is to carry potable water, it should be a free as possible of that stuff before being installed.
Begin by removing the water supply lines from your Nissan heater core. Remove the heater core retaining bolts. The heater core will come out.
The heater core can be flushed out and hopefully be unclogged. A water hose can be hooked to the heater core hoses, and water flushed through to clean the core out.
Clean out the cut with soap and water, removing debris. Apply an antibiotic such as Neosporin. Bandage it up
Drain the water from the cooling system. Remove the water supply lines. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
Tie the 2 water lines that run to heater core together
By following the NFPA 54 guide lines or the AGA or GAMA
