No Alex
Ive had two in a box for about 2 years - they had packed up after about a year or so.
I have a shrflo one that was from a carpet cleaning machine - sold as seen - with machine.
The last one was working fine on the last clean yesterday but the lads have put it on this morning and nothing at all.
I have tried the latest one on 3 different batteries - it is definately the pumps.
Have ordered 2 Shurflo pumps with Saturdaay delivery from Purefreedom but I would like to replace the switches or at least try and save one or two of them.
They are getting a hammering every day - with our work load but I would have expected a bit more from them.
When I pulled a couple apart there doesn't seem to be that much to go wrong with them, other than the switch.
