I had the filters checked about a year ago when I had a water softener melt down, so I presume they are ok.Only thing I`d check at that age is the filters aren`t clogged.
Looking at the price of a new pump they seem over a grand....Is there a competitive replacement for the one I have?yes you can get service kits but it isn't really worth it TBH. @ 17 years old, lets be honest, it doesn't really owe you anything. Time to send it out for retirement and get a younger model in methinks. Even if you replace seals etc there's no guarantee something else won't go.
Presume nothing, check everything is the way I work.I had the filters checked about a year ago when I had a water softener melt down, so I presume they are ok.
At least, some of the pipe runs are probably 25 metres.Presume nothing, check everything is the way I work.
Do you really need a 3bar pump?
