Why is my cold water line hooked up to my hot water line on water heater?
A: It is normal for the incoming cold water pipe to get a little warm due to convection – that is, hot water rising in the tank. Also copper piping is a good conductor of heat. Many modern water heaters have built-in heat traps to limit the migration of hot water.
Is there a difference between hot and cold water supply lines?
Typical plumbing for a kitchen sink includes a drain line and a pair of water lines with shutoff valves under the sink. In most cases, the hot water is on the left and the cold water is on the right.
Why is my cold water running but not my hot?
Question by time: no hot water comes out of faucets. It is only cold and the electric hot water heater is working. Another cause of very low flow would be a failure in a backflow preventer or expansion tank, blocking the incoming cold water so it cannot get into the tank, meaning little water would come out.
Do water heaters have backflow preventer?
One of the main problems seen in water heater tank installations has to do with thermal expansion tanks. Backflow preventers are now required by many plumbing codes to be installed in the cold water supply line from the street.
Why is water dripping from my overflow pipe?
When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. If the float valve doesn’t operate properly, the cold-water feed may not fully switch off, causing the water level to continue to rise above the overflow.
Why is my hot water tank pressure relief valve leaking?
Your water heater’s relief valve can start leaking for one of two reasons: either the valve was triggered to open because of excessive temperature or pressure, or the valve itself is faulty. If the problem is a faulty valve, then you might have an actual leak.
Should I use Teflon tape on water heater supply lines?
No. “Teflon tape” is used on the threads of joints, not to seal leaks outside of joints. It’s not adhesive like tape, so it wouldn’t stick to the outside of the pipe at all.
Can I replace my own water pipes?
Professional replacement is expensive, costing thousands of dollars. But often you can do the job yourself, or at least solve the worst of the problem. The elbows and horizontal pipes in the basement or lowest level are usually the main culprits. But replacing all the plumbing is really a big job.
Can you use flex pipe for water heater?
You can use flexible gas tubes or water pipes for a gas water heater in most states. If your existing gas pipe has CSST (corroded stainless steel tubes) or has not been glued, the connection should be replaced right away.
How long do water supply lines last?
Here are the expected lifespans for common supply pipes: Copper Pipes: 70-80 years. Brass Pipes: 80-100 years. Galvanized Steel Pipes: 80-100 years.
Which water line is hot?
Plumbing for a kitchen sink includes a drain line, a pair of water lines, and a couple of valves. The hot water is on the left side while the cold water is on the right.
How long do flexible water supply lines last?
“Our research shows that flexible hoses only last around 10 years and as they’re typically out of sight and out of mind, it’s not something you’re probably thinking about replacing,” said Cheryl Chantry, Executive General Manager, Short Tail Claims for IAG.
