How do I repair PVC?

[jcom]

Hello,

We are in poly country and I am working on my first PVC repair inline. We have a leak in a 200' run of poly. It is at a coupling and I don't know how best to repair as the flexibility I am used to with poly is not there.

Are there repair or splice items available for PVC?

Thanks in advance for your help.

Hey jcom-----

To repair that leak at a coupling---get a repair coupling. It's a telescopic coupling. Known as a kwik-fix or slip-fix. Supply house should know what you need. May need a regular coupling to complete the repair. Maybe can find it at the hdwe./home improvement place. See ya----

Bic has sold me on the Dawn KwikFix's.

But you can also use the old fashioned FlowSpans (slipfix).

Don't cheap out and buy one of those crappy compression fixes...Theres two types of those.

1. Ones that Leak right away
2. And ones that leak later

Many thanks for the quick reply and assist. I will get some repair couplings as I am sure I will need them again in the future.

guess that means you did find some
glad you like them. Did they have any of the larger ones in stock where you are? Web site says they are making them up to either 3 or 4". I've never seen one bigger than 1".

On a constant-pressure line, I would advise against telescoping couplings. Better to use two Schedule 80 PVC unions and a bit of sch 40 pipe.

OK , NOW I AM CONFUSED.

This is a "live" line. Can I use the telescoping coupling? I have not seen the unions???

Thanks,

Now that's some of biggest bunch of BS that I've heard in awhile. Come on out to Michigan and I'll take you to a golf course that has MANY 3" compression couplings on a 125 psi constant pressurized sch80 system. Many of the couplings have been in since the mid 80's and none have leaked. Ever.

Of the 3 pieces you are all talking about, here is my order of which leak the most often on main lines or otherwise

1. Compression repair fittings
2. Unions
3. Telescoping slip fixes

I personally use the slip fixes, and on mainline I get it extended out as far as possible. Now the thing is, any of them will do the job properly and probably not leak. But, they all have to be installed PROPERLY or they will leak. I don't like having any extra thread joints in a mainline if possible which is why I use the slip fixes. But I don't see anything over 1.5" pipe.

I used many compression couplings in the golf course back in the late 80's myself. We installed thrust blocks to prevent the pipes from moving. I only worked there 7 years so I can't really say if it lasted or not.

However...I wouldn't use a compression coupling in a mainline at a house that I serviced. I also don't think I would use a union....but I guess if I didn't have a choice I might.

Personally, I have done many repairs with four 90 degree elbows. Go ahead flame me....

I have used slip fixes in pvc and never had a problem unless I didn't get it fully extended....

I have also used the expandable slip fixes in poly....and I plan to make them better and make millions of dollars....(how do you type an Austin Powers type laugh?)
