It is made by AISITIN (model AST24‑100W, printed on the unit), runs from the plug‑in adapter in the box, and mounts on a wall with two screws. It is meant for one weak shower, faucet, or the feed to a wall‑hung water heater — not for a whole house, and not for pulling water up out of a well or tank.\u003c\/p\u003e\n\n\u003ch2\u003eWhat it actually is\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA flow‑sensing booster.\u003c\/strong\u003e Open a tap downstream and the pump senses the flow and starts; close the tap and it stops. There is no pressure switch to set. The maker’s manual says a flow of about a quart a minute (1 L\/min) or less may not trigger it, which is why there is also a manual mode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow‑voltage, plug‑in.\u003c\/strong\u003e The pump itself runs on 24 V DC.

The maker’s listing says its input is 100–240 V, 50\/60 Hz, which would cover a US outlet, but we have not seen the adapter’s own rating label, and we have no UL or ETL listing on file for it. Read the label on the brick before you plug it in; if it does not say 100–240 V, or you would rather not run an unlisted adapter, any 24 V DC supply rated for at least 100 W (about 5 A) with the same barrel connector will run the pump.\u003c\/p\u003e\u003c\/div\u003e\n\n\u003ch2\u003eWill it fit your plumbing?\u003c\/h2\u003e\n\u003cp\u003eThe ports are 1\/2 in G (BSP) thread, the standard in Asia and Europe. US fittings are 1\/2 in NPT. Both are fourteen threads to the inch, but the thread angle differs, so a hard NPT fitting can bind or leak on a G port. The corrugated stainless flex hose in the box has 1\/2 in G nuts with a rubber washer, and a washer‑sealed nut often seats on an NPT stub because it seals on the face, not the threads — but we cannot promise it for your fittings. The clean answer is a pair of G1\/2‑to‑NPT adapters from a plumbing supplier, which cost a few dollars. Plan on that and you will not be caught out.\u003c\/p\u003e\n\n\u003ch2\u003eWhat it needs to work\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA supply feeding it.\u003c\/strong\u003e This is a booster, not a suction pump.

The round button below them switches between the two. In automatic the pump starts and stops with the flow. In manual it runs on demand for a fixture that trickles too little to trigger it; the maker’s marketing says a manual run times out on its own, which we have not been able to confirm from the manual, so treat manual as something you switch off yourself.\u003c\/p\u003e\n\n\u003ch2\u003eWhere people put it\u003c\/h2\u003e\n\u003cp\u003eOn the cold feed to a wall‑hung gas or electric water heater that will not fire on weak flow; under a sink on the line to a faucet; on the supply to a shower; on the line from a rooftop solar water heater; on the feed to a washing machine or a bidet seat.
