Service Schedule – Water Softening plants/Base exchange plants. A – Site safety and regulatory compliance. - Register with security or reception before proceeding onto site.
- Register with site contact and obtain any necessary permits to work.
- Inform site of any electrical or mechanical isolations required.
- Inform site of any interruption of water supply to service (for regeneration etc).
- Inform site that site services have been restored on completion of work. Contact site responsible person. Discuss findings and actions. Obtain signature and leave completed work report.
B – Service schedule for water softening / base exchange unit. - Discuss and examine previous site softened water results.
- Carry out on site test of softened and make up water for total hardness. Establish if any change in inlet water composition has occurred since previous service visit.
- Confirm that plants regeneration capacities for both time & meter are correct and record. Record batch water meter reading.
- Inspect general condition of unit and associated plant for any leaks and general wear and tear.
- Where possible, with units fitted with pressure gauges, check pressures before and after softener Conform that the pressure on the inlet is both correct for brine draw and to achieve required flows to header tank or similar. Record water pressures.
- Inspect and service the softener control valve. Clean, grease and check all seals/diaphragms and moving parts on the control head. For SIATA, remove each piston and check/replace “O” seals, as required.
- For softeners using diaphragm valves on a manifold for plant backwash and service flow eg. S.E.D valves, these diaphragm valves are to be randomly inspected and made good as necessary.
- On a least an annual basis, remove the softener head or vessel connection to access the softener media and check resin bed depth to assess any loss of media. Take a sample of the resin if required to establish if resin is cracked or fouled (organic or inorganic).
- The standard service specification does not include for the removal of the larger man-lids on steel units but can be included if required (please contact us for this option.)
- Where applicable, check and dismantle brine draw valve, educator and brine check valve.
- Check strength of regenerant (brine).
- Carry out a plant regeneration for the purpose of establishing ;
- Correct brine draw and air checkCorrect salt tank refillPerformance of control headsMedia loss during backwashSolenoid operation where applicableReturn unit to service and confirm softened water outlet quality.
- Identify and bring to the attention of the site responsible person any areas for improvement or items needing attention, either imminently or at the next scheduled service visit.
- Leave a report on site with regards to the above and obtain a signature and confirm the next scheduled service visit date.
Service Schedule – Filtration plants. A – Site safety and regulatory compliance. - Register with security or reception before proceeding onto site.
- Register with site contact and obtain any necessary permits to work.
- Inform site of any electrical or mechanical isolations required.
- Inform site of any interruption of water supply to service (for regeneration etc ).
- Inform site that site services have been restored on completion of work. Contact site responsible person. Discuss findings and actions. Obtain signature and leave completed work report.
B – Service schedule for filtration unit. - Discuss and examine previous site filtration results and outlet water clarity.
- Check input water quality for clarity. Establish if any change in clarity has occurred since previous service visit.
- Confirm that plants backwash time interval is correct and has not been altered.
- Inspect general condition of unit and associated plant for any leaks and general wear and tear.
- Where possible, with units fitted with pressure gauges, check pressures before and after filter and record pressure differential. Record water pressures.
- Inspect and service the filter control valve. Clean, grease and check all seals/diaphragms and moving parts on the control head. For SIATA, remove each piston and check/replace “O” seals, as required.
- For filters using diaphragm valves on a manifold for plant backwash and service flow eg. S.E.D valves, these diaphragm valves are to be randomly inspected and made good as necessary.
- On a least an annual basis, remove the filter head or vessel connection to access the filter media. Check freeboard to assess no loss of media and to establish that the media has been reclassified during backwash.
- The standard service specification does not include for the removal of the larger man lids on steel units but can be included if required (please contact us for this option.)
- Carry out a filter backwash for the purpose of establishing ;
- Correct backwash flow ratePerformance of control headsMedia loss during backwashSolenoid operation where applicableReturn unit to service and confirm water outlet quality.
- Identify and bring to the attention of the site responsible person any areas for improvement or items needing attention, either imminently or at the next scheduled service visit.
- Leave a report on site with regards to the above and obtain a signature and confirm the next scheduled service visit date.
