2 Technical Questions on the Adaptor 1" hose to 3/4" BSP

Question

Greetings I am looking for some pipe fittings to convert my UK caravan. Do you sell pipe connections to join 28mm waste pipe (grey) onto a 1 inch bsp thread? I couldn't see one on your waste pipe list...I want to connect the existing waste pipes into a ball valve. Regards, Steve.

Answer

The closest that we can offer is our part 133363 which has a 1" nozzle suitable for fitting to the 28mm pipe with sealing sleeve 118708. The other end of the fitting has a 3/4" BSP thread (1 inch diameter) which you may be able to adapt to your ball valve. Remember a 1" BSP thread has a diameter of approximately 1 1/4".
If you have a 1" BSP thread in your ball valve then you should be able to get a male 1" bsp to female 3/4" bsp adaptor from a plumbers merchant.

Question

My motorhome's waste water outlet "beer barrel" tap restricts flow. The waste water pipe is black ridged flexible pipe and the outer diameter of the threaded part of the existing tap is 26mm. Should I go for your part 138084 or 125321 for fastest emptying? If 125321 then which adaptor do I need to connect to the flexible pipe?

Answer

I would suggest that you use part 125321 together with adaptor 133363.
