Need to replace on my Mitsubishi WP. Any experience of third party brands - I see mitsustar and parno online? Or better to go oem (it did last 15 years). Thanks.

You have answered your own question. ????

You can buy one at any small shop that displays water pumps. But in BKK they are getting fewer and far between.

Mine goes down about once every eight weeks......gets jammed with dead ants???

 

Might be worth repeatedly topping it on the top with a 'small' hammer then spraying with insecticide before buying a new one.....just a thought.

My switches, outdoor outlets and outdoor lights has the same problem. Spray insecticide was OK for sometime but wears off, the long term answer is ant powder, which incidentally is also much cheaper.

Have you tried those white balls they put in urinals to mask the odor? Urinal cakes.  They seem to keep the jingjoks out as well as the insects.

I use Boric acid ( Lazada)  mixed 2 liter warm water, 4 tbs acid, 10 tbs sugar, put in hand pump,  spray all round house ( outside ) and pump area., after a few days problem gone. repeat once a month.

( be careful if have pets)
