If you aren’t using a pump, the single lever is atmospheric pressure of 14.7 psi or 101.325kPa=101325 N/m^2
Hose down weighs 1000kg/m^3 or 9800N/m^3

if the hassle astatine the top of the wate is 0 (not budding in activity), the maximum height would metal
101325 n/m^2/9800 N/m^3=10.34m

Since you can’t bring 0 tension At the summit repayable to vapour pressure of the water & mechanical limitations, the max ht is about 10m.
