Postby Breizh29 » Thu Jan 19, 2017 6:17 pm

Is this glue OK for 13.5 pipes?

I have a doubt :roll:

Do you mean the quantity or quality?
There is nothing else on the market here that i can see. I australia its a two part process, first a cleaning solvent-usually pink and then the glue is applied-blue.
Here its just clear glue. I would use far more than necessary to ensure good adhesion. Just clean off the excess.

The main concern using Thai-Pipe solvent for uPVC is to use a fresh can, If the container has been opened and stored for some time the solvents will be affected by air introduced to the can causing it to go off enough to stop proper solvent welding. If it has the consistency of glue it is long passed best by date.

Hi Andyfteeze.

I was talking about quality and for the pipes used for the pool discharge nozzles.

Thanks BKKBILL,
Do you think it's OK for swimming pool if a fresh can is used?

I do not think there is any problem. Important is to have the glued parts well clean, the best roughing up with a fine sand paper. And the glue well aplied on both parts.

Thanks Klondyke.

Sorry I saw this thread a little late.
I use this.

pvc glue
In my humble opionion this is the best glue I ever used. Bought it at hardwarehouse at the phenomonal amount of 850 baht per can .Used 2 already and need 1 more.
The color is gray so you can see always where you glued. Also has a very rigid sponge that can be used all along.

For swimming pools, never use the thin, PVC solvent cement sold in all hardware stores. It is only for 8.5 grade pipes and is not designed for use in the 13.5 grade high pressure PVC pipes used in the swimming pool industry. It does come unstuck and the worst thing you want is when it happens under your pool floor or under your patio with its expensive tiles or sandwash.

There is generally only one brand available in Thailand but it is certainly not stocked everywhere and never in general hardware stores. It's a SCG brand (Chang) product and it should be in stock therefore in any main HomeMart store or if not, they will order it for you. It's also available online from some pool stores. Look for Chang solvent cement.

It is also the only cement that will allow you to mix normal "blue" PVC pipe with this ABS type of pipe, especially good for connections that are under pressure

I am using the simple solving cement in the green box (as shown on the first picture above), available in different sizes in every hardware shop. And in more than 10 years I have not experienced any failure.

I asked my pool builder to use this glue and he does. But I'm sure this is not the one he usually uses on all other pools. He uses the glue of the first photo and he made swimming pools for twenty years! :roll:

I cannot agree. As I mentioned, with me it has been working OK for many years. And in my 25 years here I have never come across of other PVC glue in the general hardware stores. Admitted, I have never asked for such.

BTW, as far as I know, there is no water pressure in usual water pool equipment. The water driven by the pump thru the filter goes freely out from the numerous outlets, inside and/or outside the water level. Never against a close valve. Unlike as at house water system where the automatic pressure pump pushes against closed faucets. A certain differential pressure occurs after the pump outlet before the sand filter, however, this is very low.

The pipes under the pool bottom are quite sufficiently protected when embedded in the concrete. The water will surely go out rather by the free outlets 2" than by a leakage in the fittings.

The only concern at the PVC pipes are where they are exposed to sunshine (I have some, still working after 11 years). However, rather cracking than leaking in the fitting connections.

In this one I'm totally 100% on Jazzmans side. The cheap all available green glue will NOT stick for a long time. I have experienced several pipes going lose, in the water supply of my house.
It is crap. Use chang!!! Also available at hardware house and I even could buy small handy tubes at the local mom&pop construction shop.
What else to say to people who know everything better just because they haven't seen the problems they might have.

btw back in town and nowhere to go anymore. Finally retired.
