I have a 1986 19' Bigfoot
, I keep it in good condition and it gets well used. For the last few trips I have noticed the cold tap in the bathroom handbasin is leaking up through the valve stem. the water eventually drips into the storage compartment under the basin and into the belly and escapes through a drain hole. It is not in a location where damage will occur if I can cure the leak soon.
I have replaced the Tap washer, the "O" ring on the stem and the packing washer to no avail and I am pretty sure the 22 year old tap is just plain worn out. I have tried plumbing shops for a new valve assembly to screw into the existing tap body without success.
I am now pretty certain I will have to change the whole assembly (two taps mixing into one spout and a shower take off). I am sure I can get a new tap as a similar unit is used in modern Bigfoot
campers and maybe trailers.
The problem is the Bigfoot
has a moulded Fibreglass bathroom inside a moulded outer shell. There is a storage locker with a small door below and to the side of the underside of the bathroom handbasin. I am unable to see or even feel the underside of the taps assembly to undo the nuts on the old tap set. I am sure a dealer can perform the job but I am hoping someone else has already solved this problem and can give me some hints or suggestions. Thank you.
