I have two Ecotech Vortech MP10 ES pumps for trade for an MP40 WES. The exact manufacture date is unknown, but they're from 2012. This is because after removing velcro, double-sided tape due to moving; the sticker on the back is no more unfortunately. I contacted Ecotech and asked if there was any other way to find out, this is what they told me:
"Thank you for contacting EcoTech Marine and I'm sorry to hear about the situation. The other other way you would be able to tell the serial number from that MP10 would be to program the pump using a ReefLink and EcoSmart Live. That said, ESL is only compatible with MP10wES or wireless VorTechs and you will be unable to determine manufacturing date. If you have any other questions, please let me know."
With that said if you're going to upgrade them to wireless then you could find out the exact manufacture date if you really wanted to. If you're interested, please PM me. Thanks!
