Seems cities could easily be held accountable for increasing pressure

Nope, in our code it states the homeowner is responsible for maintaining 80psi or less to the residence.

I don’t believe it’s been increased, in these neighborhoods it’s always been around 125

Owner refused a pressure reducing valve.

Hook a fire hose up to that!!

Found some of the pictures of a pvc water line that was ripped out of the ground by lightning.

Customer called with water shooting 15’ in the air after a thunder storm.


Pieces of the pipe was scattered around the yard.

Not a picture, but a video of a plumbing fail & the guy installing it doesn't seem to know it.

You may be able to see one of the fails from the still image for the video.

 

[Twowaxhack]

He needs two pipe diameters between the weir and the vent. He’s built a crown vented trap.

@Zanne @Twowaxhack - OK, please explain for those of us (ME) who are ignorant :O)

Won't the pex lines be pinched between the drywall and drain pipe?

 

[Zanne]

Hamberg, in the still image for the video the trap arm is almost nonexistent. It is too short which creates a crown vent. A crown vent is similar to an S-trap in that it allows water to be siphoned out of the trap.

(IPC) 909.3 Crown vent
A vent shall not be installed within two pipe diameters of the trap weir.
If you watch the video, he does a couple more things wrong. For one, the trap weir appears to be more than 18" above the floor but the pipe above the trap is not a full 18" (or at least does not appear to be).
(IPC) 802.4.3 Standpipes.
Standpipes shall be individually trapped.
Standpipes shall extend a minimum of 18 inches (457 mm) and a maximum of 42 inches (1066 mm) above the trap weir.
Access shall be provided to all standpipes and drains for rodding.
UPC (not sure of code section)
No stand pipe receptor for any clothes washer shall extend more than thirty (30) inches (762mm), nor less than eighteen (18) inches (457mm) above its trap. No trap for any clothes washer stand pipe receptor shall be installed below the floor, but shall be roughed in not less than six (6) inches (152mm) and not more than eighteen (18) inches (457mm) above the floor.
Lasly, he did not install a cleanout on the vent.

Twowaxhack, those cuts/holes are ugly!

Ferdinand, I couldn't tell. Apparently the builder already screwed up by making the wall 2x4 instead of 2x6 so he had to add additional furring strips to make the frame thicker for the stuff inside. I know more about the DWV side of things than the water supply side. It looked like at least one of his crimp rings was put on slightly crooked- although I might be mistaken.

Most of the comments in response called out the crown vent. I replied with the specific code info (which I have saved in a post on my plumbing code stuff tumblr blog).

I really should update that blog at some point.

 

[Twowaxhack]

On second look that might not be crown vented.

Look at the extended trap weir. It’s longer than some.......


See how short this one is....

 

[Zanne]

I think that was the dry fit. He squeezed them pretty tight together when he did the final fitting IIRC. I could be wrong though. I just don't like how short it is. LOL.

Right, the fitting is made longer than the one on my truck. The one the guy uses in the video is longer, this allows you to butt the fittings hub to hub without it being a crown vent.

If you put the one I have pictured you couldn’t put them hub to hub or it would be a crown vent.

That’s how I see it.

 

[Zanne]

Ahh. Ok. I personally would want more space in between the hubs because I like to leave room for repairs if anything leaks. But, that is usually more of a problem with water supply lines (like the PVC crap in my well shed).

 

[Zanne]

This is the back of my washing machine. Not sure what the rusted spots are or what caused it. Possibly cat vomit... Really don't know. I'll have to see if I can clean it off safely when we get to working on the laundry area. I'm trying to figure out what the plastic thing to the right is for. some sort of vent?

I agree, I like leaving room between fittings too if it’s possible. It’s good practice.

 

[Jeff Handy]

That thing might be a vent, or maybe a lint trap of some kind?

Change your supply hoses to burst proof braided type.

I didn't see any primer before he glued.

 

[Zanne]

That's another good point, sawguy.
Jeff, Thanks! We plan to replace the supply hoses. Not sure if we already bought some, but I will look for the braided steel ones.
Btw, are hammer arrestors still necessary on the shutoffs? I've seen some say they are no good and others say they are needed.
