cross over

[metx]

I moved a water heater about 2 feet from where it was .Now i am getting cross over in the kitchen not up stairs . I also rough in a new bathroom in the basement about 3 feet from the water heater . They never had this problem before ,can it be the old hot water heater(about 30 years old) is to high temperature .and can be crossing over . or do i need to put a check valve on the line , also the water is about 3 feet away from the hw .The inspector will inspect the bathroom not the wh .next week sometime

We use copper flexes in E. Quake country. Ialways loop My cold, so the hot doesn't travel
up and out

Just moving a water heater does not cause crossover. To be more specific: Since you moved the W/H, you ? are getting hot water out
a cold water faucet? Did you move any tees, or just extend existing
lines?

[glkearns]

Could be that the tub/shower valve that you roughed in is on, and the spout/head nippels are capped. Cross over city. Make sure the mixing valve is off and see if that helps.

I agree with glkearns.... good catch!

[boillerman]

Yup, good catch. The new Delta has a cap, you pick the cartridge later with the finish. Causes a crossover. I just read "moved the W/H" and scratched my head.

Just close the integral stops then.

[JCsPlumbing]

No integral stops. Guessing but alot don't have them. I like it when they do.

Integral stops = code

[JCsPlumbing]

Which code?

Not NPC......and I'm pretty sure NY is NPC like KY is.


Every integral stop I've found on shower faucets were "after" I had already turned the water off, and most all of them could not be turned off due to calcium buildup.


Of course, you could back them out and clean them for the next time....


I'm the kinda guy that one valve shuts it all down. :check:

NY state code says you must have integral stops on a shower valve. Why wouldn't you want a shut off on every fixture?

Ahhh, it's a good idea, not saying it isn't. But they are concealed/hidden and most times on a Delta or Moen you can do a full rebuild without removing the cover plate.


That goes in line with other valves as well.

In my experiences though, those stops never provide a permanent seal to shut off water. It's like any other valve that was installed initially and not touched for years before being used.


Most of the 600 series Delta shower valves I run across had the integral stops.

I agree but the code is the code.

in a multi unit building (2 or more units) every fixture has to have a shut off. very few multi story buildings have individual services to each unit.

angle stops count as a shut off. tubs and showers require an integral stop.

the only fixture that seems to sneak by is a laundry hose bibb. they tend to look at it as a stop. but truthfully the hose bibb will need new packing or replacement.

as far as being able to shut the valve down the road. i find that if nobody has messed up the screwdriver stop with a bad fitting screwdriver. i can usually get them to turn and shut off. honestly i have more issues with angle stops shutting off than a screwdriver stop.

I don't generally use them unless it's a multi-family building. I'm always surprised when I do use them and they actually work!

Does it have to be an integral stop by code are can you still put in ball valves if there is an access panel ?

I couldnt see an inspector shooting you down for a ball valve instead of an integral stop. So I will guess and say that would be acceptable. Good Q.

[metx]

Just passed inspection on bathroom , I had to ball valves feeding hot /cold in bathroom. AND CAPPED WC and sink .will put shutoff today .
