is it an S-trim? if so since its there have them upgrade it to the SI-trim. Its a new impeller, bearings, seals and i got a new volute as well for ~$700
MUCH better blower than the S-trim
I seem to be hearing vortech wont rebuild the s-trims really anymore because they are trying to phase it out as the new SI-trim is in full production. almost everybody ive spoken to and read about that has sent in an s-trim for rebuild has been denied and told they cannot and will not rebuild it. theres absolutely NO reason they couldnt rebuild it unless the case itself is ruined along with the shafts and gears, impeller, bearings and seals. that way you need a new blower but anything short of the housings being broken, all other internal parts are replaceable.
