Steve Q Posted April 26, 2022 Share Posted April 26, 2022 If you've bought this with 30 days from a dealer then I'd be returning it pronto as you have 30 days to get a full refund.

Daveeck Posted April 26, 2022 Author Share Posted April 26, 2022 Sadly I've has it more than the 3 months warranty the dealer supplied Quote Link to comment Share on other sites More sharing options...
Daveeck Posted April 26, 2022 Author Share Posted April 26, 2022 I am hoping it's as simple as the pvc valve Quote Link to comment Share on other sites More sharing options...
Steve Q Posted April 27, 2022 Share Posted April 27, 2022 Worth a shot. I'd also recommend a diagnostic check. Quote Link to comment Share on other sites More sharing options...
