Honwave- leaky airfloor valves
I'm hoping someone can help. I have a year old Honwave T38 which had lots of use last year in the Thames and has been excellent fun. I keep it inflated (with a little air let out) in our garage. The problem is i noticed since i owned it that the high pressure air floor slightly deflated over time when left inflated. Recently it has got a lot worse and i'm finding that over about 2 weeks the high pressure floor is gradually leaking air out and the right hand floor chamber is completely deflated after only 2 weeks (the left seems to leak air much slower probably over 9-10 weeks. I've checked for leaks and upon spraying soapy water i can see some small bubbles around the outside both the air floor valves. Is it possible to refit or replace the honwave valves and does anyone know any place that will do this?
I don't think the boat is under warranty etc is it worth contacting Polymarine to see if they can help? I live in Reading so am looking a place reasonably local ie South or Southeast to try and fix it.
I'm really hoping it is fixable and assuming it is how much should it cost?. I'd rather get it fixed professionally than attempt to do it myself.
Appreciate any advice. Thanks!
