I have a Spectra Cape Horn Extreme 330 - 2 Shurflo pumps to a single
It is now 5 years old, and I think the membrane has gone, as I cannot get the quality better than 1000ppm even though the pressure is around 90psi and all other vital signs seem ok.
Can anyone point me towards a supplier of non-branded membranes please?
I am sure that I have been told that this is a standard item, which can be ordered in US from the internet
(I am currently in the Philippines
, so I would like to order the part before opening up the unit.)
