Each kit includes a siphon tube with filter, mounting bolts, shaft key, and instruction booklet to get your machine back in action as quickly as possible.

Powerful unit when it works

2 months ago
Pressure dropped and noticed water spraying out around the soap outlet area. Further inspection revealed this crack. Worst part is I can’t find the proof of purchase receipt and this is the second time that using it.

Died on my Simpson presser washer after two years.  Now I have to buy a new one 1/3 of the price of entire unit🤦

No, I do not recommend this product.

Picture and product differences

a year ago
Picture and product are different. Actual product has vertical pressure adjuster and caused modifications to be made to framework. The picture's horizontal position would have fit without issue.
