How do i replace this broken and leaking A7 valve? It seems to be stuck into the recessed rubber moulding. Do i need to take the whole moulding out to get at the valve, and would it be very difficult to glue the rubber moulding back in place after i've changed the valve?
Any advice appreciated!
if you cannot repair the valve in situ ,the best bet is to cut out part of the recessed mounting leaving the outer ring still glued into the tube this then allows you to cut a round patch with a C7 valve fitted in it and glue it to the tube over the outer part of the recessed mounting which gives a better base to glue and roll to
Paul knows far more than I do about these things.
But just like he’s suggested I have in the past cut out an old valve and glued a new one in place which was already mounted in a circle of Hypalon.
It’s a bit tricky keeping it all flat and not gluing the tubes sides together but perfectly achievable by a competent amateur.
If it's just the 'mushroom' you need to replace, there were some very good instructions on RIB Shops website about how to do it with the body of the valve still in place in the tube. I followed them myself and found them easy enough to carry out.
Unfortunately my internet access at work won’t allow me anywhere near the ribshop website to post a link.
Hi,
Thanks for the advice, my problem is that the actual body of the valve has been damaged, and the valve has been glued into the recessed moulding so i can't just change the diaphragm.
So i think i will have to fit a new valve on a hypalon patch as Paul has suggested, thanks for your help.
