The manufacturers in Canada may provide technical support. Local electricians or plumbers may be of asistance but it is possible that they are not familiar with this specific technology.
Additionaly, the manufacturer provides a user manual, which offers advice on measuring flow rate, determining head, and guiding the installation of the system, although the directions are fairly complex and require some technical expertise. Not all parts necessary for complete system are included in the kit
Bearings in alternator are recommended to be replaced yearly and should be available through any bearing distributor. It is recommended to have a bearing press and properly sized mandrel, plumbing components can be sourced through other plumbing supply stores.
