I need to replace the pump on my Jabsco 29090-2000 in my C320 because of base cracking. :{ I am considering instead installing the Raritan Sea Era electric head, with pressurized water feed. Do you know if I will have to install a new outlet hose to the holding tank, or will the existing hose reach and fit? Also, does the Sea Era come with an adequate one-way check valve for the water inlet, or should I install one myself? Finally, are the base bolt holes similar between the two units, or will I have to drill new holes? Many thanks for any assistance.
