Supply Plumbing

At present we are not able to supply ALL the plumbing components required to connect and regulate pressure to your Sumisansui setup.

We are supplying all the crucial and hard to find Sumika brand components from Japan and we can provide advice and alternate suppliers for pressure regulators and filters but supply plumbing is up to you. The Sumika start connectors can be connected to readily available NPT (National Pipe Taper) fittings, though the fit is imperfect and requires several wraps of teflon tape

A pressure regulator, or a gate valve + pressure gauge on the downstream side, is required to achieve correct coverage and to protect the Sumisansui system from overpressure damage. Pressure regulators must be selected in function of your flow rate, which is a function of how many metres of tubing you are supplying.

We are actively working to find more complete solutions for pressure regulation, filtration, and adaptation to the Japanese thread pattern and we look forward to providing more options in the near future

    For now we encourage you to source the parts you need locally or online based on the following:

  • The R-tube start connector for R-wide Sumitube presents two threads, 1-1/2" ext/male and 1" int/fem. Both work adequately well with NPT fittings but the 1-1/2" seems a bit more snug.
  • Filtration to avoid clogging the pores can be achieved with the filter socks we offer or any upstream filter equivalent to 80 mesh (180 micron)
  • R-Wide must be protected against pressures in excess of 30psi (0.2bar).
