Polyplumb fittings must not be dismantled for any reason prior to jointing.

 

Procedure for using the component pack of spares

 

Dismantling the joint

Step 1:

If it is necessary to remove a jointed pipe from a fitting, the cap-nut should be unscrewed and the pipe with all the socket components present on the pipe end should be pulled out of the socket of the fitting. The pipe end complete with all the socket components should be cut off and discarded. A complete component pack of socket spares should be fitted to the socket as described below and pipe jointing should be carried out as described in the installation section.

Replacement components

Step 2:

The component pack (Code: PB95XX) is supplied as a cap-nut with all the socket components present in the correct order and retained by a retaining cap.

 

Preparing components

Step 3:

Completely remove the retaining cap, ensuring that the socket components remain within the cap-nut.

 

Replacing the components

Step 4:

Without removing any of the socket components from the cap-nut, introduce the cap-nut and socket components to the socket of the fitting and tighten up the cap-nut by hand ensuring that the components enter the socket without snagging.

 

Checking the fitting

Step 5:

Carry out a visual check to ensure that all socket components are present in the correct order as shown in the diagram and table, and that the rubber ’O’ring is lubricated. If in doubt, the ‘O’ring should be re-lubricated using Polyplumb silicone lubricant.

 

Fitting the joint

Step 6:

Carry out pipe jointing as described from step 3 onwards.

 

Reduced component fittings

 

Changes have been made to 15mm Polyplumb couplers, elbows and tees and 22mm Polyplumb elbows and tees, which need to be considered when using Polyplumb spares kits with these fittings, as follows:

 

Original Polyplumb fittings

Step 1:

If the bottom white washer is present in the fitting below the grab-ring, then the spares kit can be used as supplied without making any changes.

 

New Polyplumb fittings

Step 2:

If there is no bottom white washer present below the grab-ring with one of the five listed fittings then this is one of the fittings which has been modified.

 

Before the spares kit is used, the carrier moulding should be carefully removed from the cap-nut and the bottom white washer should be removed and discarded without changing the order of any of the other components. After this has been done, the spares kit should be offered up to the socket of the fitting within the cap-nut, inserting the components into the socket in the order they are within the kit and then screwing down the cap-nut onto the outside of the socket.

System testing

Prior to completing installation it is necessary to fully test the installed system. Please refer to the section for system testing guidance for further details.
