hot tub glue and primer

The Glue used by many hot tub manufacturers is Weld-On PVC 795

The Primer used by many hot tub manufacturers is Weld-On P70

When gluing with PVC glue ensure the fittings are dry and above 60 degrees Farenheight or a leak may occur due to poor contact from moisture or cold temperature curing causing the reaction to not chemical bond the two surfaces correctly.

Clean both surfaces thoroughly, make sure to not use primer on flex pipe.

Apply glue to both surfaces making sure the glue is covering the complete surface area that will make contact, any voids in the glue may cause leaks. Assemble the two fittings together (ensure that the end of pipe is cut clean and straight) by twisting the pipe slowly clockwise in to the fitting until it bottoms out.

Hold the new glue joint for 30 to 45 seconds, check the complete circumference of the glue joint to ensure no voids or areas did not receive enough glue to squeeze out confirming a water tight seal.

If a void or an area appears to not have received enough glue you will need to start over. To avoid this costly and time consuming error use extra glue when applying the glue.

Allow 30 minutes curing time for a secure bond.

If gluing in an area that you can not dry and has moisture present use a water resistant glue that will react in a moist area to help ensure a good glue joint.

Make sure any ridged PVC fitting is clean free of imperfections, then primed with primer to assist the bonding process.

Do not use primer on PVC flex pipe, the primer may dissolve too much of the surface of the flex pipe and cause a leak.
