The ShowerPowerBooster is fitted to existing pipes and there are many potential problems with existing pipes which make the choice of a compression joint the best choice. We have chosen compression joints for ShowerPowerBoosters because they are the easiest joint to fit and avoid leaks. It will seal against a pipe which has ovality or is wet.
In order make a successful leak free joint it is important to understand the function of each component of a compression joint as putting plumbers mate or tape on the wrong component can even cause a leak when there would be no leak. Too much plumbers mate or tape can block the filter so we advise you to use tape and plumbers mate sparingly. Plumbers mate or tape on the right components is essential for some customers.
All ShowerPowerBooster are provided with a mesh which is held in place with a black rubber seal. This has 100% to do with holding the mesh in place to prevent particulates blocking the flow switch. This has nothing to do with stopping the joint leaking
A ShowerPowerBooster is supplied with a 3 part reducer so you can fit the pump on a 15mm pipe as well as 22mm which standard copper and plastic sizes in the UK. If you live in Southern Ireland or you have old imperial pipework you can replace the 22mm UK olive with a 22mm to 3/4 inch conversion olive or replace the 15mm olive with a 1/2 inch olive.
In explaining the function of each part of a compression joint I have chosen to illustrate this with reference to a ShowerPowerBooster fitted to a 15mm pipe using a 3 part reducer. For fitting onto 22mm pipe its much more straightforward as its only the 22mm olive and nothing else that would benefit with plumbers mate or tape.
22mm Chrome Plated Compression Nut – The chrome plated compression nut screws down and compresses the olive to create the seal. It is important that the screw thread is not encumbered by either plumbers mate or tape as this will stop it creating the force required to compress the olive and correct the ovality of the existing pipe if this is required.
Compression Nut Conversion Insert – This is part of the 3 part reducer supplied free of charge with a ShowerPowerBooster and it is only required if you are fitting to 15mm or 1/2 inch pipe. It transfers the force from the 22mm chrome plated nut when screwed clockwise to the olive. It is fitted between the 15mm olive and the nut. It is important that this component is not encumbered by either plumbers mate or tape.
15mm or 22mm olive- The olive fits copper and plastic pipe and always benefits from plumbers mate or tape being used on it.
22mm to 15 mm Taper –This is part of the 3 part reducer and is only required if you are fitting to 15mm or 1/2 inch pipe. The outside of the taper seals against the inside of the showerpowerbooster which is also tapered and this this is a component which always benefits from plumbers mate or tape being used on it.
