FREQUENTLY ASKED QUESTIONS
- QUESTION: I have a header tank in my house that is very noisy while filling, will the Hansen Mini Fast-Flo valve be any quieter?
- ANSWER: The noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The valve outlet doubles as a spigot so it can be attached as a length of hose to allow the flow to be placed onto the bottom of the tank eliminating this noise.
- QUESTION: I have found the rubber seats in the compact trough valves I am using don’t last very long, does the Hansen Mini Fast-Flo valve use the same rubber seat?
- ANSWER: No, the seat we use in Hansen Float Valves are urethane which is a very durable and hard material. The seal is also reversible if a foreign body should damage it.
- QUESTION: The pressure at my compact trough is quite high and the compact float valves I have used either don’t last very long or they don’t shut off properly. Will the Hansen Mini Fast-Flo Valve work with high pressure?
- ANSWER: Yes, both the Mino Fast-Flo and Fast-Flo Valve has the arm pivot point positioned to allow closing at pressures up to 12 bar (174psi). And for Fast-Flo Valve with a 115mm float attached.
- QUESTION: What size tank inlet do I need to fit the Hansen Mini Fast-Flo Valve?
- ANSWER: All Hansen float valves carry a 25mm (1”) female thread on the valve inlet. This gives you a couple of benefits. The valve will fit inlets from 15mm to 50mm when using our range of adaptors. The additional material used at the inlet to form the female thread strengthens the valve at an area that has been identified as a weak point in other brands of valves.
- QUESTION: Will the Hansen Mini Fast-Flo valve work in my calf shed bowl troughs?
- ANSWER: Yes, the Mini Fast-Flo was designed as a compact valve for use in small bowls, compact troughs, feeders & header tanks or any situation where the valve space is confined.
