Mitsubishi Water Pump - time to replace?

[dinga]

Am 99.9% sure there ain't no option but to replace - but worth a check.

 

Our 13+ year old Mitsubishi Water Pump (connected to standby tank) has been used for watering our smallish garden (every 3 days or so) and to supply household needs when the government water supply is off.  So it hasn't had much use over that time (has a cover over it to protect it from the elements), but we are very close to the sea - which I reckon is the cause of the problem.

 

The pump's pressure tank has sprung a leak through a rust spots (I had thought the spots were only surface ones - clearly that is wrong!).  I reckon repair is out of the question - especially given the age of the pump.  Correct????

Unless you can replace that particular part best get new and protect it from the salt air.

You can repair the pressure tank, as you call it, using a self tapping screw some old innertube and some epoxy. It won't last forever as you will eventually spring another leak. 

A new tank from a pump shop is about 1800 baht. Stainless a bit more. 

Just tell them the model number. WP-xxx

I had the same problem with a Mitsubishi pump. The pressure tank was replaced with a new stainless steel tank from lazada. Also replaced the plastic straw and washer that goes into the tank, along with new gaskets on the intake and outflow.

Great - thanks.  Did the parts come with the tank - or did you have to get them separately?

Let a repair shop take a look at it and see if they can fix it, my grandfather-in-law has a mitsubishi pump that's well over 20 years old and it still working to this day, even with occasional trips to the repair shop.

Thanks everyone (especially Banana7).  I've ordered a replacement S/S tank via Lazada - hopefully that'll keep the pump operating for a few more

years.

Update:  Replacement S/S tank arrived in a couple of days, and has now been fitted and the pump reconnected.  Famous last words I know, but everything is performing perfectly (long may that continue).

 

Thanks again for saving me around 7k !!!!
