Changed out an 80 gal electric today. Connected the hose and cracked the valve under pressure to clear out the scale, then shut it off and hooked up the transfer pump. As soon as I started to open that plastic drain valve, the dang thing blew apart and shot water and scale all over the carpeted hallway.

I managed to jam it back together enough to stop the flood. Pretty sure I cross threaded it in the process. I despise plastic valves. 馃が

Anyone else had this happen to them?

How about flooding city hall? 1st year apprentice and my mechanic told me to hook up the hose to a big water heater and to drain it, I didn't know what the hell I was doing until the whole drain cock came out. They were scrambling to find a shut off valve which wasn't there.... 6"inches of water later....

Our bottom drain cock are opened using a flat head screw driver. Unless it's those freaking off brand diy specials. Those are booby traps.

I hook up the pump first then open the valve to prime the pump. Plus the plumbers here install the heater with a brass drain cock still using a screw driver to open/close. Those I haven't had any issues.

What kind of valve was it?

I've had issues, but I live in UT so the water here is liquid sandpaper

As an apprentice we were working in the youth detention Centre, after we shut down and drained the heating system, i was told to crack open up a union, to see if the system was empty, so We could change a valve...
nope the pipe sheared off just above the floor and over the next few mins it started to flood out the first floor and cells..
it was a nightmare, I ended up using a wooden wedge(that held the door open) to drive a rag into the 1鈥 pipe to stop the flood of water.
in the end it was a learning experience and a good story to tell the grand kids(which I don鈥檛 have yet..).
This type of thing only makes us stronger, as long as you learn from your mistake.

The british navy still teachers their sailors to plug holes in the hull(say that 10 times fast!) with a bag of wooden wedges.

Those plastic drains are an insurance claim waiting to happen. When they give me even the slightest impression that they are brittle I drain what I can from the T&P into a bucket. Then I unscrew the T&P and put a rubber washing machine hose that I cut the end off of into the tank and hook that up to my transfer pump and avoid the crappy drain all together.

those valves have been around for 40 years and have been a horror show for plumber
and homeowner alike.....

I had one fellow where a set of skis fell over in the mechanical room and snapped off
that valve on the way down to the floor...... full pressure shooting across the room and
flooded the hell out of his house before they could shut the heater off.....

Smith and whirlpoo both have them on their newer heaters and they seem to be much
stronger than the older ones from long ago..... you just cant get them to drain when
their is sediment in them....

Yep. I'll usually grab a bowl or a bucket, and then hot swap a bv. I don't even mess with that garbage anymore.

I think those plastic pieces of sht need to be illegal. Its absolutely ridiculous.

I heard this many times on this forum but what I don't get is what happens if the threads of the plastic drain cock were to snap off? 70 gallons end up flooding the place or worse it's on a 3rd floor condo complex damaging the apartments below too.

It's getting me to think that I should maybe drain them from the top in condos if they are plastic. Never had an issue though with these :

2 summers ago a guy was installing shelves in a closet and his drill fell on the plastic valve and it snapped off. Him and his wife spent the entire night using towels to soak up the mess and they showed me their blisters on their hands... I had to extract the broken plastic. Told the guy you should of went and bought a shop vac.

I don鈥檛 remember if this was a 40 or 30. Plastic drain down. 2nd or 3rd floor in a 20s apartment building. It turned into a bucket job. On the plus side, I was able to change for cleaning the tub drain.... we put the valve back in once it was light enough to move down the stairs.

.............brass valves rule
Of course brass is better. We install state and they all come with brass.

But nothing is foolproof. I was snaking a drain at a school and hooked my hose to the drain valve to flush the waste line. Went to shut the drain and when I tried to shut the drain it wouldn't. Phocking anode rod wire was stuck in it!!!! Tried pushing it back in with hot water coming out to no avail. I ended up screwing my 3/4" ball valve with garden hose ends on! I was pissed. That was ~5 years ago. Our guys changed that heater a month ago and no one knows where my valve ended up!!!

I couldn't shut the cold off because it was a bank of 3 heaters with one valve and it was 30mins before lunch time so the cafeteria kitchen was using tons of hot water. That valve and hose adapters was only like 2 months old.

I had a call for a leak in the ceiling of a selectman's office a couple years back. I happened to be parked on main street 100' away. I stood on his file cabinet to look above the drop ceiling. Heating system boiler drain was slightly dripping, they had just started the heating system for the season a couple days prior. Pulled out my pocket hose cap, screwed it on gudentite, and I was done. He grinned and asked "That's it?! You're still charging me the hour minimum aren't you?".
