I run tfr through mine and sometimes hypo but it's followed up straight away with pure water for rinse/scrub - as yet I haven't seen any premature failures - that's not to it's recommended - I'd check with exceed
I did this with gardiners back pack and it's ok to run chems as long as it's cleaned but the warranty is void
So, take your pick ease of use compared to having to splash out 35 quid
