Viton/US check valves - Problems

[m4drx]

hi guys,

I am wondering how many of you have had problems using the above.

I have noticed that more and more people are having problems using them and i have found mine to stick closed if not used for a short period. They seem to be well worse than stock.

any thoughts would be good to see.

Had them on mine for a while and not had any problems?

Where did you find the imformation that more and more people are having problems with these?
 
Had mine on for about a year now and not had any problems so far...Far better than the standard ones IMO

How many check valves are there in the system. Are there more in the pre 99 than post 99 ?

4 check valves in total in the stock rats nest.

Viton are far superior to stock T. I cant see the check valves causing the problems it may be another component that is misbehaving. Maybe the stock check valve just covers up the problem?

what do they do???

Mine have been fine but i\'ve only got 2 checkvalves in the ratsnest anyway so if they fail, i have the other 2 viton valves spare.

what do they do???

Basically they only let air flow one way...

i know what you mean mate and at a tenner from the us it makes sense to buy but random people ive spoken to, many that dont use the forum or just dont post the problems and also the occasional post on here etc.

just made me wonder thats all as i am certain the block up with lack of use.

Not used my FD much for six months, no problems at all with Viton check valves,
