Vortech Mp40?

[Scythanith]

My MP40WES's are extremely quiet when they aren't ramped up above ~90%. I have two of them on the battery backup and have had zero issues with them. I clean (soak in vinegar) the wet sides maybe once every 4-6 months.

Yupp +1! The "trick" to keeping these pumps quiet and running is to clean the wet-sides.

Slyguy00: you may also want too look at the new Tunze 6095 wide flow pumps.
