Solar Water Fountain Pump system only - HDB OK (new or used one) in Tampines Street 92, East Singapore for sale

The photo you see is what I have done in my HDB house, a DIY solar fountain.   So HDB - is OK with this solar.
Discount to clear the last 2 new ones this few week.  Selling NEW in the box - $40,  used one working in the picture $30 (only one).  Different from previous batch, for those who have bought. SAFE with children and pets.   More importantly,  Green and save maintenance costs.
Power comes from sunlight.  A solar panel with long cable could extend out of the window  was what I had done for in door.   With no direct sunlight, fountain is weak, when cloudy day or night,  the fountain  will take a rest, and alive the next sunny morning.
Item is available unless I removed the ads, so need not ask on this.
