help with pressure on an outdoor shower

[nibhelim1]

hi folks,
my parents have a big tank on top of the roof of their garage. the tank gets warmed by the sunlight in the summer and we use to take outdoor showers. the problem is that there is little pressure of the water that comes out of the shower head, since the only thing pushing is gravity. Is there an easy solution for increasing the pressure without breaking the bank? there is easy access to electricity since is on a garage, but it has to be waterproof since is outside. thanks for the help!

Have you tried changing the shower head

Remove any flow restrictor in the head
Create a head modeled after black bag camping shower kits

I did, brand new one improved a bit the pressure but still is quite low

Raise the tank

Raise the tank

that is not an easy thing to do, it's already on top of the roof...

Make sure the tank is full.

an inline pump might work

Original poster, you do understand that height relates to pressure and that, say, your tank is 10ft. up, you will be getting 4.33 psi ? It is easy to measure pressure with a gauge.
There is a world of equipment/pumps.

Yeah, you are never going to get a lot of pressure out of a gravity system without a lot of head, and modern showerheads aren't made for high flow, as low-flow is the more usual requirement. Hey, I know, lower the showerhead! 8*)

Not sure if this will break the bank, but a 500watt $50 Vevor power converter and a $58 rv water pump (search online) might improve the pressure. The wiring and connections would be not much added cost.

Nice catch, I knew someone would have a good answer!
