    We've just had our submersible pump replaced with a FloJet 'Triplex Diaphragm' R3426-500
    The flow and pressure to the taps and toilet are now good but the shower is still poor.
    The shower is at the end of the line so to speak - behind the loo at the back of the MH.
    I've tried to take off the shower head to look for grunge but couldn't see anything.
    Would a replacement head and pipe be the answer?
    Can't think what else to do. In our caravan we got a reasonable flow to the shower - we know not to expect anything like a domestic set up but this is too trickly for comfort.

    Hi Mags did you run the shower without the head on ?Try it to see if you have pressure :thumb:If still no pressure try looking for kinks in the pipe leading up to the shower - if you have good pressure at the taps etc then you should have virtually the same at the shower :thumb:
    Is there an adjustable switch on the pump ?to turn pressure up ?
    My shower in the van out performs the house shower :Wink::thumb:

    Just a suggestion,,, take the shower head of the pipe and see if you are getting a reasonable flow through the pipe on it`s own,,, if you are I think a shower head with less holes or a smaller shower head may be the answer..

    What was it like before you put the new pump on,, or didnt you try the shower ?

    Thanks for replies. It was very poor throughout the MH before we got the new pump. We had it replaced because the old pump was letting in air. Flow without the shower head isn't good either. I'm starting to think there must be a kink in the pipe somewhere. How would we find the pipe leading to the shower or is it a workshop job?

    Hi Mags

    We had the same problem as you ok pressure at sink but no good at shower so we changed the pump thinking thats what it was. New pump was just the same then someone suggested swaping the wires around as it was a german pump and maybe reversed polarity. We did this and shower works fine so even the first pump was wired wrong and to make it even better we have a different shower head we use when showering as found the one in motorhome wasnt great.

    Hope this helps and makes sense

    Be very carefull when trying to increase the pressure on your mh or caravan plumbing system.
    The pipework is designed to operate at a given pressure. Any increase in this pressure may result in a busrt pipe. The smallest leak in a hidden pipe can cause you more trouble than enough.

    Hi,
    First question, do you have the model number correct, only on searching Flojets site I cant find any mention of a FloJet 'Triplex Diaphragm' R3426-500.

    Here's their data sheet: http://www.ittflowcontrol.com/files/Triplex (81000-384).pdf

    The thought does occur to me, is your pump definitely a 12 volt pump. Only ask this as they do both 12 and 24 volt pumps in that line. A 24 volt pump on 12volts would certainly give you the reduced performance you are experiencing :Blush:

    It is a 12v pump for certain.
    I'm confused about the idea of reversed polarity as it is a 12v system. I thought the polarity issue was on the mains. Or am I missing the point?
