Service 101 Water King
Service is important • Service after the sale defines your customer commitment. • The service technician is the point of personal contact with the customer. • Sales personnel need to participate in service and start up to connect themselves with the equipment they sell. Water King
Types of service calls • Service calls for parts plus labor. • Warranty determinations. • Warranty repairs. • Start ups. • Equipment surveys leading to quotations. Water King
Required service skills • Troubleshooting • Valve calibration • Valve rebuilding Calibration Trouble shooting Rebuilding Water King
Before you leave the shop • Review reference material for O&M. • Call customer and make arrangements. • Determine softener model numbers. • Troubleshoot the problem over the phone. • Take parts. • Establish billing rates procedures. Water King
At the jobsite • Establish contact with company representative. • Gain access to the location. • Meet and greet as necessary. Water King
Ask the operator. Don’t touch anything until you, Water King
Ask the operator: • What was the reason for the call out? • What in particular is different than previously noted? • What does he believe the problem to be? • When was the last time he added salt? • How often does he normally add salt? • How much does he normally add? • What has been done to try to remedy the problem? Water King
Ask the operator: • When was the last hardness test? • Does the problem seem to be common with both columns? (If twin) • Ask for the log sheets. • Ask operator to review the piping arrangement. • Ask if it is possible to bypass the system and not disrupt facility operations. Water King
Make as many observations as possible. Don’t touch anything until you, Water King
Observations • Does the unit have power to it? • Is the service light on? • Does the unit have salt in brine tank? • Level of water in brine tank? • What is inlet and outlet water pressure? • Is piston is service position? Water King
Observations • Any flows to drain? • Is time of day set correctly? • Take a water sample – in and out. • Conduct TEST. • Does it match the operator log sheet? • Which unit is on line? Water King
Observations • General condition of equipment. • Condition of wiring. Is it corroded or damaged? • Metered system – When was last regeneration? • Does meter work? Is it registering flow? • Is supply valve to softener open? • Is bypass valve open? Water King
Make certain it is OK to start cycling softener.Re-Check with operator. Don’t touch it yet!!! Water King
Now you can touch unit.Start repairs. Water King
Take unit out of service • Prove your problem. • Go SLOW. • Open bypass valve and close outlet valve(s). • Inlet valve to remain open. • This will prevent unwanted water or salt in effluent supply. Water King
What will happen? The five cycles • Service. Raw water passes “down flow” through the resin bed. • Backwash. The resin bed is fluidized loosening the resin particles and removing suspended matter captured during the service cycle. • Brine Draw. A brine solution is applied “down flow” to the resin bed removing the hardness ions from the resin matrix. • Slow Rinse. The brine is rinsed from the resin bed at a low flow rate to reduce water use. • Fast Rinse. The resin is rinsed at a higher rate to remove all brine from the bed. After the fast rinse cycle, the softener is on Standby until returned to Service. Water King
Problem:Hard Water, not using salt. • Determine model number and find out regeneration flow rates. Water King
UBLE SHOOTING TROUBLE SHOOTING Water King
Initiate Regeneration Water King
Initiate regeneration • Initiate regeneration from timer. This will put unit in backwash position. Water King
Backwash • Observe piston position. • Observe flow to drain. • Measure flow if possible with bucket and stop watch (Ref required flow from catalog or O&M.) Water King
Backwash • Flow rate low: • Low water pressure. • Plugged backwash flow control. • Other restriction in backwash lines. • Flow rate normal: • Move on. • Recheck brine level measurement. Water King
Advance cycle to next position Water King
Brine draw • Observe flow rate to drain. During this cycle all water that is going to drain is passing through injector. • Flow rate to drain will be much lower than backwash rate. Water King
Brine draw • Flow rate to drain low… • Low water pressure. • Plugged injector. • Clean or replace. Water King
Brine draw • Flow rate to drain high... • Water is bypassing injector. • Injector not properly seated. • Piston broken or leaky seals. • Unit out of calibration. Water King
Brine draw • Flow Rate to drain normal... • Move on Water King
Brine draw • Recheck brine level measurement. • Brine should be drawing a minimum of one-inch per minute. Water King
Brine level not moving • Disconnect line between softener and brine tank. Put finger over tube. • Poor Vacuum: • No vacuum or pressure from control valve. • Problem is in the control valve. • Injector, piston, or BW flow control problem. Water King
Brine level not moving • Good vacuum • Good vacuum will be obvious. Seems to get stronger and stronger with time. • Problem is in the brine tank. Water King
Brine level not moving • Brine tank problems – brine valve • Cracked • Dirty • Plugged • Clean or replace brine valve Water King
Advance cycle to next position Water King
Fast rinse • Full service flow passes to drain through backwash rate of flow controller. • Observe flow to drain. • Use white paper or styrofoam cup to check for resin to drain. Water King
Advance cycle to next position Water King
Service • Observe valve position • Service light should illuminate on valve • Shut off kit should open • Open bypass valves • Unit is returned to service Water King
Other problems Water King
Salt in service line • Problem is from poor brine draw. • Too long to get in so it is never rinsed out. Water King
Salt in service line • Plugged injector. • Low water pressure. • BW flow control restriction. • Fast rinse not long enough. • Pressure drop in front of unit. Water King
Salt in service line • Variations in inlet water pressure can cause problems. Need good constant pressure. • Problems may occur under 40 psi. Water King
Mineral to service • Unit installed backwards (up-flow). • Broken distributor. • Mineral in BW pit. BW flow control failure (BW rate too high) or broken distributor. • Repair or replace. Water King
Insufficient service flow rate • High pressure drop • Bad Resin • Draw sample and inspect • Shut off kit not fully opening • Clogged distributors Water King
Troubleshooting SOK • Aquamatic valve vent restricted • Ruptured diaphragm • Asco valve not operating properly Water King
Aquamatic valve drawing Water King
Twin units: One hard, one soft • Check brine director valve. • Check brine director. • Remove one side at a time to verify correct operation of director. • Clean or replace. Water King
Brine tank overflowing • Foreign material lodged in BV seat. • Remove and clean. • Float binding on brine well. • Realign. • Faulty BV seal. • Replace BV seal. • Fittings defective. • Tighten or replace. Water King
