Q: Why should I buy a Honeywell branded actuator when you have a compatible one considerably cheaper. Why I ask is that I am now onto my third replacement.

A: Some people do prefer the Honeywell branded one. If they are failing regularly, then I would recommend fitting a 40003918-007 repair kit as well as a magnetic filter (like a Magnaclean) and making sure you have enough inhibitor in your system.
Q: Could you please tell me what the warranty period is on this item. Thanks

A: It is the longer of 18 months from date of manufacture, or 1 year from date of purchase.
Q: Hi Manager, I did replace powerhead 40003916-003 yesterday. Now when I turn on for hot water central heating is also getting hot. Could you please advise. thanks. Jose

A: It could be a wiring issue or the valve body could be stuck.
