Quality product
It works just great. I bought this to rebuild my very old 5 stage Mako system. Honestly I didn't know how it worked and after replacing a few things it wasn't working properly. The engineering dept is top notch and spent a lot of time trouble shooting and walked me through the whole thing. Iended up replacing everything and it's now like a new system.
