Previously sold as T-PF.P01C (also known as Tecma 36750) — same pump, updated part number
OEM replacement discharge and macerator pump for Thetford Tecma Compact Line marine and RV toilets. 12V DC. Grinds and discharges waste — max vertical head 4m (13.1 ft), max horizontal distance 40m (131.2 ft). Recommended fuse: 30A. Replaces T-PF.P01C and Tecma 36750.
The Thetford Tecma Compact Line toilets — including the Nano, Compass, and EasyFit models — rely on the MAC 4 motor-pump unit to macerate and discharge waste from the toilet bowl. The pump grinds solid waste and pumps it through the discharge hose to the holding tank or overboard connection. When the pump fails, slows, or stops, the toilet cannot discharge — making it one of the most critical replacement parts in the Tecma sanitation system.
The 50114 is the current Thetford part number for the same pump previously sold as T-PF.P01C and Tecma 36750. The part number changed when Thetford's distribution was updated, but the pump itself is identical — the same MAC 4 outlet pump, 12V DC operation, same discharge performance specifications, and same compatibility with the Compact Line toilet family. If you are searching for T-PF.P01C or Tecma 36750 and landed here, this is the correct current replacement.

Max horizontal discharge distance of 40m (131 ft) and 4m (13 ft) vertical head — suitable for most marine and RV installation layouts
Runs on 12-volt DC power — compatible with standard marine and RV 12V electrical systems. 30A fuse protection recommended
This pump has been sold under multiple part numbers over its product life. All refer to the same MAC 4 discharge pump: Current Thetford Part Number: 50114 Former Thetford/Tecma Part Number: T-PF.P01C (also written T-PF-P01C) Former Tecma Catalog Number: 36750 The part number changed as a result of updates to Thetford's distribution and catalog system. The pump itself — its dimensions, electrical specifications, discharge performance, and toilet compatibility — is unchanged. If your service manual, parts diagram, or existing pump is labeled T-PF.P01C or 36750, the 50114 is your correct current replacement.
