Fixing pin hole in hot water line exiting water heater?
If copper, drain the water out of the pipe, clean the spot and solder over the hole. Steel, either replace a section of pipe, take apart and reassemble making sure the joints have enough dope or teflon tape on them to seal.

you want your cold line coming tying into both inlets on the water heaters and the hot lines tied onto the outlet side of the water heaters evenly (so they get even draw and o…ne water heater doesen't have to work harder tnan the other). your recirc line coming in ties into the cold line in beetween the two water heaters with a circ pump going twards the cold line and the other end of the circ line tying into the hot line on the furthest fixture. on the cold line coming in you need a ball valve, check valve and expansion tank before it ties into any of the heaters. NOTE: The solution above is for tanks in parallel not in series.
We don't , what we do is call the manufacturer or just replace the heater entirely so as not kill anyone over a defective installation
A lot less because the water is flowing if it is exiting and it depends on the water pipe size.
No If the hole is smaller then the diameter of the supply line
There should be a non return valve on the cold water side of the hot water tank. When there is no non return valve the water in the tank heats up and expansion of the water wi…ll cause it to travel backward up the cold water pipe thereby equalising the waterpressure normally this expansion would find its way out of the safety pressure valve. So it sounds like the non return valve needs fitting or replacing.
most water heaters rust out from the bottom or at he top where the pipes lead into them. the amount of time and effort to try and fabricate a fix would not serve the owner un…less he had no choice. replacing the unit is the standard way to fix these. sometimes the gas regulator can go bad and these can be replaced.
It is called this as it heats up or brings up the temperature of cold water to hot. In other words, it is producing hot water by heating it. Some people incorrectly believe it… is redundant to refer to "hot water" and "heater", but there are many other types of heaters, so the distinction of one creating hot water is entirely proper.
Perhaps after the repair was completed the water source was not completely reopened, or perhaps the part with the pinhole was replaced with a part with a smaller inside diamet…er (I.D.).
Need to replace hot water lines. Do you need to turn off the hot water heater if you shut off the main water line?
Yes. I would. If you are replacing the hot water lines, it is also a good time to drain the hot water heater and get rid of all the junk at the bottom of the hot water heater.… That should be done once a year. Your hot water heater must be off when you do that, your hot water heater should be off when you drain your hot water heater. You will see boiler scale come out of your water heater. Leaving the boiler scale in your water heater makes it less efficient. It makes it harder to heat your water. It is the same as throwing money down the drain. If you want to give your money away, you should give it to the Salvation Army instead of the Utility Company.
The two pipes going into the heater should be marked with either Hot and Cold or a H and C. There should be a shut off valve on the cold side, but sometimes there is one on bo…th sides. If the piping is visible, you can follow one or the other to where it comes into the house. The water heater is usually the first thing the water line runs to.
Your HWH usually is not the problem, most likely the problem is at the faucet. Older homes or home where the mineral content is high can have "buildups" of minerals in the fau…cets, valves and even restrict the diameter of the pipes. If you have any galvanized pips, check those first. The valve closest to you sink will probably be a good place to investigate. Sometimes it can be as simple as removing the aerator, from the faucet, then opening and closing the valve (both valves, the one of the faucet itself and the one below the sink) This may dislodge some of the mineral buildup. Then replace the aerator.
You could drain the line, sandcloth flux and solder it. Otherwise, see if you can get a compression fitting that would fit the copper tubing
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.
You haven't said what's wrong with it.
There is absolutely no point. -You would gain more efficiency by using one larger tank, and it would be much cheaper .
you should dig the floor.
This depends on the size and model line in question. Basic models start at around $200. Deluxe, or larger tank units can run over $1000 and even more for commercial operatio…ns.
