Installation of a Rubber Pipeseal

Fitting a Pipeseal

Step 1. Mark on the tank where you require inlets and outlets. On of the benefits of these tanks is that there are numerous points on the tank where you can fit pipeseals. It is very simple to fit pipeseals to these tanks as they are made of Polyethylene which is easy to drill.

Step 2. Select the correct pipeseal for the required pipe connection, then select the correct size holesaw. This is very important because if you use a hole saw thats too big, then you will not get a water tight seal. If the correct sized holesaw is not available, then mark out the pipeseal circle on the tank and cut through the tank carefully and as neat as possible.

Step 3. Once the hole is drilled, deburr the edges of the hole which will help insert the pipeseal.

Step 4. The Pipeseal should now be inserted into the tank hole which should be a tight seal.

Step 5. Spray WD40 onto the inside of the pipeseal so that your pipe ‘slides’ through the pipeseal.
