I have single lever faucets...
Some of my faucets (not all) mixes the hot with the cold...

Meaning if i turn the lever all the way to the cold side,, the cold water is not ice cold and every once a few seconds you can feel some look warm water and not cold
 
What kind of faucet is it? Delta? Moen?
If it's a Moen, there's a plastic cartridge inside that needs to be replaced.
If it's a Delta, there's two or three O rings that need to be replaced.
When these items wear, you get leaks. YouTube is your friend. Very easy repairs.
 
You have parallel piping, the pipes are close to each other and not insulated so there is heat transfer to the other pipes.
This should go away if you run the water for a while, right?

The solution is to separate the hot and cold water pipes with insulation or space.

Sorry, I misread the post and answers. Agree with 1304cc above

Mine was caused by the mixing valve installed on our new water heater. Out with the mixing valve, cold water is back! Before it'd run cold for a few second, then warm for about 8 seconds, then cold for the rest of the time. Waste of water. Removed the mixing valve and bumped the temperature down on the tank.

After looking into my heater.. I am guessing i have one of these valves.. I do not know what is the purpose for installing these?

Did you remove yours yourself?

No, my cousin is good with that stuff so he removed it for me. I believe he said it's against code to remove them now? It looked pretty simple other than our water shut off valve coming from the city was corroded right through so they had to come and replace the valve so we could shut the water off (free of charge). My cousin added a bunch of shut off valves (incoming, outgoing), so we can isolate the hot water heater separate from the rest of the house, for future maintenance.

The mixing valve mixes cold water with the hot water as it exits the tank. I think they use it so you can keep the water in the tank at a much higher temperature, and then it cuts it with cold so a) you don't scald yourself and b) you use less of the hot water in the tank to achieve the same temperature water so your hot water supply lasts longer.

We have a gas water heater and it can recover the heat quick, so no real need to conserve the water in the tank. I bumped it down to "vacation" temperature and it barely ever comes on now, where before it was coming on every few hours, even if we didn't use any hot water. I'd imagine we're saving quite a bit of energy now!

Anti-scald valve, IIRC they became mandatory a few years ago. Keeps children from burning themselves.
 
Watch out with reducing the temp, look up legionnaires disease to find out why.

If not all of your faucets have problems with hot mixed with cold, I would look for the problems in the faucets. To confirm, run a suspect tap (on full cold) wait until you get your warmish water and then turn off the hot isolation valve under the sink, if the water gets colder, you are sure it's the faucet.

Replacing cartridges is easy, it's a good start once you narrow the problem to the faucet.

3 faucets are okay and 3 faucets are not
