I SEE TAOBAO. their stuff is extremely cheap. however do note of the shipping costs involved, especially the agents in singapore go by the 500g.
another agent i use other than sgshop is 65daigou.
you can ask and place orders with them at sim lim towers. sometimes they do not have it in stock as not many people buy. else you can try getting it online, perhaps ebay. you can save alot, but the downside is the waiting time.
alright, thanks bro! will head over to daiso to get this product when i pass by. was thinking if cutting those cookerhood mats to use it, but too troublesome, your idea is great!
pluck it our from your toilet bowl
you can youtube some auto top ups. most reefers use gravity fed, but that means you gotta have a container to store all the water as well..
this works by using a pump to pump it up, means you need ac supply, while yours is using gravity fed. depends on what you are looking to top up, if you're topping up your sump, gravity ones might just do it's job.
it tops up using a pump from the liquid container when the float switch is switched on when water level drops.
i suppose that the acrylic container is provided as well as i see a separate float switch, which could be for the water level in the liquid container.
