Hi,
The time has come to replace all our sanitation hoses. The engineer wants to install an anti-syphon vent for the forward head. Whilst this seems to make sense it does create a much longer pipe run. We have IP420 hull 4 which is 15 years old. She's been ours for 8 years and we've not had a problem, and we have to assume IP knew what they were doing not installing one, but attitudes and knowledge do change. Any thoughts, advice, comments much appreciated.
Thanks
Lindsay
