PVC swing type check valve, wafer type: prevents back flowing of water in pipe works.

You have to release check valves regularly to prevent overgrowing - especially for sea water uses. Clean them regularly to prevent malfunctions.

For smaller diameters please choose simple check valves.

Installation instruction:

Check if the PVC tube easily fits to the fitting. If the connection is too tight grind the fitting and/or the tube with sand paper to ensure mobility.
Work only in a good ventilated room.
Cleaner and glue are inflammable and their gases are heavier than air.
Do not smoke - do not weld - prevent spark formation and electrostatic charge - no open light and fire.
Do not inhale - keep used cleaning paper in closed boxes - wear protective gloves - keep away from children.
Cut the tubes rectangular and bevele and trim the ends.
Clean the surfaces of fitting and tube with PVC cleaner. Therefore put a little bit of the cleaner onto a paper towel and wipe the places for glueing carefully. Fat and dust has to be removed totally.
Coat the glue on both glueing places - first in the fitting, secondly onto the tube. For tubes with diameters larger than 40 mm (1.25") choose a larger glue container with application brush. The following bonding should be done without delay. Diameters larger than 90 mm (3") should be executed with two persons to reduce the open time of the glue.
Push the tube totally into the fitting without torsion or twist. A correction is - if even possible - only feasible for a very short time depending on the tolerance of fitting and tube.
Wipe away surplus glue with a paper towl.
After about 2 hours at room temperature you may startup the operation (pressureless). After 24 hours at room temperature the full maximum pressure is achievable. Lower temperatures extend the curing time.
Flush the pipework before using.
