Replacement / spare Bullfinch shower head and hose for Bullfinch external shower point ideal for caravan motorhome boat van cabin

Like many users of this product I use it for washing the dog and cleaning muddy boots.From the same waters source the pressure from this shower head is not sufficient to clean a muddy dug or muddy boots.Removed shower head and replaced with the old very much used shower head and all is fine.Very dissatisfied . Definitely unfit for purpose.
