View Full Version : "Hot" Repair

As usually happens on this forum a situation will be discussed and then something similar happens to one of us. We had a cracked 3/4" main line that supplies a planter near a cafeteria building (very old school) that is on domestic water and is hooked into the cafeteria water somehow. We were unable to find an isolation valve and turning off the cafeteria (even for a short time) was not an option so I had to make the repairs "hot" so to speak. We dug a large enough hole that we could set up our Honda pump to handle the water and then I glued in an open PVC ball valve. After letting it set up for about 15 minutes I was able to shut it down and reconnect the line.

Here's some pictures. Please excuse the primer/glue mess. I had to work between pumping surges and wanted to make sure there was plenty on the pipe and fittings. :)

When you said "Hot" repair, that's not quite what I expected to see. :laugh:

The water was warmer than the drizzling rain that was coming down at the same time. :)

Why not use a compression-end valve? Not in the budget? :p

Purp...When you say "supplies planter", is that to a faucet or irrigation?
I'm wondering about a classic cross-connection.

Why not just use a compression coupling?

Funny, I just posted about having to do that with a 2" line.

Exactly what I was thinking, and I am sure Purp would think of it too and make sure that was not the case in that situation.

Any damage done to Purps brain cells was done years ago. He is almost functioning at full capacity now, however he does lapse occasionally and that is why we have to keep a close eye on him at all times. Plus he's cute and I like to keep a close eye on him anyway.

she...you'd asked about "Lawn Genie" beer..it's a formaldehyde/mescaline
based .5% sold by big box stores to counteract the effects of glue sniffing.

No no! After a hard day in the trenches sniffing glue, there's nothing like
a candlelight dinner of zebra mussels & "good old Lawn Genie".

I've been in that situation a few times in a commercial setting. Even have had the Fire department roll because of the pressure loss alarm for a fire suppression system.

So with that said, I would say that under the conditions that Purp was in, what he did was the most cost effective solution.

Compression ended valves or coupling, with water flowing, get that sand or mud on the groves, whether it be plastic or brass would be just about impossible to tighten properly.

Also, that is the purpose of fast setting glues, so if you need to, then you can do that kind of repair.

Now a most likely situation, that globe valve was probably all they had on hand at the moment. So, you have the capacity to fix that repair now or do you drive and lose over an hour to find that compression end valve?

Just giving my imput....

Everything's in the budget... I just go and buy what I need. :)

Answer: no room; 3/4" line was butted right up against the 1-1/4" line.

Not on your freeking life! It has to be a MAJOR problem for me to have to work overtime. I am a government employee. I would of let the 3/4" leak go all night if I'd had to. It wasn't a gusher until I cut the pipe to make the repair. Besides... the cafeteria is used for after-school YMCA programs and the restrooms would have been shut down also. :)

It supplies MPR-1000s in a planter.

It's cross-connected unlawfully thanks to district plumbers that originally ran it 30 years ago. Hell... read through the threads and you'll find one where a new cafeteria building and irrigation system was installed less than four years ago on domestic water and no BF was set. Oops... oversight. I'm still trying to get that one straightened out.

Would of been glad to except for the other pipe. :)

Ever try and install a compression coupler on a live pipe? It'd better be 105 degrees and I'd better be wearing Speedos (ugly thought) for the dousing I'd get. :laugh:

Naw... Just late getting around to everyone's smartazz remarks because I had a baseball game to umpire right after work. This will be my last year doing that too. Hate strapping on the carbon fiber brace for my knee and then all the plate gear on top of that. :)

Shush... You'll get people to talking and they'll vote me out of the forum right along with you. :nono:

Right on John! This school is in the extreme northeast sector of the district and our suppliers are located extreme west and extreme south... prolly 15 miles one way. It got done and the leak was no longer. :)

Boy this was fun... got to pad my stats a little. :laugh:

Nah,

Everybody that responded before me did give... well sort of a proper answer. But I guess because I don't always have the time or the space for proper equipment, I'm use to using what I have on hand.

Sometimes the better way isn't always the smartest way to do something.

By the way, I said this before(in jest) that I pay your wages anyways. Now I get to complain how you're wasting Northern CA water, but even that isn't true because your area gets most of the water east of you.

Yep. I've done many that way. I spent a short period of time working on city water mains. The repairs to breaks in the mains were always done with water flowing. The issue was the water could not be shut off completely without a boil water advisory being issued (restaurants and other food related facilities would have had to shut down until the advisory was lifted- $$$). We shut down as much flow as the health dept. would allow us. It was a real treat in the winter.

i have had to do that on numerous occasions.
here's a trick so you do not have to have a pump going.....

take a section of pvc pipe and glue it (or insert without glue if needed) to the other side, and use the legnth of pipe to carry the water off to a distant location, then glue the ball valve on the problem pipe.

I'm a believer that if Plan A doesn't work move on to Plan B and right through the alphabet. When you get to the end of the alphabet then just start over with Plan AA. :)

I usually never have to go past Plan C and only then because I've encountered something unplanned. You never know what you're going to run into until you get it dug up and exposed.

LOL... We've been known to piss in the California Aquaduct and the Friant-Kern Canal so those downstream have an interesting life experience. :laugh:

If I don't use the pump they'll think I don't need it and will take it away from me. :laugh:
