Sorry for the delay in responding. Our boat is currently for sale and as such have not used the Spectra Setup I put together for several years. It would need a new membrane - but the design is straightforward and easy to operate. We enjoyed it, and were we still sailing - I can be certain still using it.

Be sure you have an adequate size intake and maybe consider dual filters (intake) to each of the 12v pumps. There can be flow loss with too small an intake and only one filter. We up-sided the valve and thru hull. Thank you for the drawings comments - glad they are helpful.

Best of luck in building yours. Cheers - Jim

Hello,
I found your Spectra post. Do you continue to use this system? How did it work for you? Is there anything you would have changed with your design? I acquired a similar system on a budget and am considering duplicating your process. Your drawings and explanations are fantastic.

Thank you for any time and input,

Best Regards

Steve
