## Customer Reviews

### ⭐⭐⭐⭐⭐ Fit great. Must adjust pressure valve -easy
*by K***N on June 6, 2025*

Perfect fit for 2020 ish Troy Built 2800psi 2.3gpm unit with Briggs and stratton 8.75.Before installing the new head, apply a little grease to the 3 black rubber holes. That will allow the new one to slide on without damage. KY or astroglide will work great if you don't have silicone grease/wheel bearing/general purpose, ect.The ends where the hose and wand attach had extention blocks for my Troy Built and will need to be removed from the old head and added to this new head. This allows the end connections to stick out of the front of the unit futher. You dont have to do this, but it will make the connections easier to access.The hose inlet has some lock tight and is very difficult to remove. You should remove the head from the old unit. Put old in vice and then install extension blocks on the new before you put it on the power washer.Its much easier to remove/install OFF the unit.Adjustment of release valve is a must. NOoOOo this isn't broken. You're brain is lazy and broken. You didn't READ.It specifically says you will need to adjust the pressure release valve. Grab a 10mm wrench for the nut (shinny silver one). It must be loosened first. Then use a 3mm Allen to turn out the set screw if your unit it turning off.You can turn in the set screw about 3 full turns from all the way out and it will be a close adjustment.Good luck!! 👍

### ⭐⭐⭐⭐⭐ Works
*by A***T on June 30, 2025*

Worked as needed. The hard part is finding compatibility chart. There should also be provided adjustment procedure. However, procedure by another reviewer worked great.

### ⭐ Not A Great Replacement for my Generac G0071320
*by J***S on December 9, 2024*

Lube up the 3 rubber washers before installing on the pump head!!! I didn't and had to reuse 2 of the 3 old ones because they got damaged when testing it after first installing it.There were numerous replacements available and this one seemed to most closely represent what I needed. Works as it should. Had to removed the soap feed nipple as the spring & ball behind it weren't installed correctly from the factory. Considering the work to remove and replace the pump, that was no big deal at all.06/13/2025 Update: Finally used it about a month ago. The soap feed pumps water out, causing water to overflow and spew out of the soap container. Unless you cap the connection, the pump is constantly having to build pressure back up every 5-8 seconds if you're not using the wand.
