Tim T Posted August 30, 2020 Report Share Posted August 30, 2020 (edited) Morning all. Having a moment of self doubt so would like some info please! Attached below is a photo of the chassis mounted PRV on the 5. Can somebody confirm what the return pipework to the tank comprises, in terms of gauges and threads. Many thanks, Tim Edited August 30, 2020 by Tim T Additions Quote Link to post Share on other sites
John L Posted August 31, 2020 Report Share Posted August 31, 2020 I have just done this, unfortunately looking at the invoice it doesnt tell me what the part was, I took the PRV off and took it Pirtec a hyrdraulic fittings company and matched it up. You could perhaps ask KMI who make the PRV, I'm sure they would tell you. I have changed my pipework from the CAV filter, and run that return line back into a new fitting in the top of the tank.

Tim T Posted August 31, 2020 Author Report Share Posted August 31, 2020 Thanks John. I will see if KMI will tell me. The hose though is 1/4 inch? Thanks Tim Quote Link to post Share on other sites
tr graham Posted August 31, 2020 Report Share Posted August 31, 2020 Tim cannot give you the thread size of the top of my head , but I can say that the return pipe does not return to the tank it returns to the filter in the boot . graham Quote Link to post Share on other sites
John L Posted August 31, 2020 Report Share Posted August 31, 2020 I used 8mm internal, I was trying to the larger size of the return into the tank to make sure it wasn't restricted. John Quote Link to post Share on other sites
Tim T Posted August 31, 2020 Author Report Share Posted August 31, 2020 I have a Bosch pump in the wheel arch Graham, so I think that it does go to the tank? Tim Quote Link to post Share on other sites
tr graham Posted August 31, 2020 Report Share Posted August 31, 2020 Tim if you have gone non standard then yes you will have to put it back to the tank and either get a later six tank or put another inlet in your 5 tank graham Quote Link to post Share on other sites
Tim T Posted August 31, 2020 Author Report Share Posted August 31, 2020 Got the new 6 type tank so should be ok with the connection. Cheers Tim Quote Link to post Share on other sites
