Make sure you use hose clamps at all the connections to insure that the hoses do not pop off due to the high water pressure. The collection cup at the top should be the same diameter as the main reaction tube. It is applied with a needle applicator for the thin watery mixture and with a larger hypodermic needle for the thicker cements such as the Weldon brands. Make sure the humidity is low and the temperature around 78-80 degrees where you intend to do the glueing. Please wear gloves and goggles to protect yourself as these glues can bond skin and eyes instantly.
Some people are also sensitive to having htese substances touch their skin.
PVC tubing can be glued with the special PVC glues available in most hardware stores. You must first primpe every piece before glueing as this will increase strength and prevent leakage. PVC is extremely easy to glue but once glued it is permanent like acrylic. So make sure the pieces fit properly first before applying the glue. A drain can be provided so that the collection cup emties into a seperate container by means of a hose and hose fitting.
