No maintenance man needed.
Easy to do, took about ten minutes, five to find my glasses, five to install.
Hydro Spin has only four spray settings, that's OK with me, what I was going for was a long hose, so it will spray up and down and all around! I will be able to bathe Kandi in the shower! She loves the water anyway, I had trouble keeping her OUT of the shower in the rig. She wanted to shower every time I did. Otherwise a quiet Sunday.
