    In practice, a system can almost invariably be made to perform more efficiently if further re- commissioning is carried out on site. Please note that engineer visits by Dutypoint are priced at one visit to commission one pump set. If there are multiple units on a site, special terms can be negotiated. To arrange a commissioning visit, please call the Technical Service Help line 01452 300590.
