Surge Pressure Allowance
December 28th, 2022
202304A – AQTTB Date Issued: 18 April 2023 Polypropylene piping materials are inherently fatigue-resistant and can often accommodate cyclic pressures exceeding the long-term pressure rating of the piping system. There are two types of surge effects to be considered. The first is a more gradual, intentional recurring surge, such as when a VFD-controlled pump is Read More
Tight Clearance Wrenches and Aquatherm Fittings
December 15th, 2021
202112A – AQTTB Date Issued: 15 December 2021 The Aquatherm NPT transition pieces, both male and female, are sometimes difficult to get a standard wrench on to the brass shoulders of the fitting.

Butt fusion heating and cooling times DVS 2207-11
August 20th, 2020
202008A – AQTTB Date Issued: 12-Aug-2020 The standard referenced for butt fusion of polypropylene pipe, DVS 2207-11, was updated in 2017 to provide for reduced heating and cooling times. During the revision process, these changes were not evaluated for multi-layer, faser-composite (MF) pipes. Aquatherm has now completed the testing and evaluation of these changes and Read More
Aquatherm Threaded Adapter Fitting Installation Guidelines
December 18th, 2019
201912A – AQTTB Date Issued: 12 December 2019 Aquatherm offers a wide range of threaded transitions to connect with non-fusible system components. These transitions have a machined brass or stainless-steel threaded insert molded into the PP-R base for maximum strength. The brass transition components are lead-free (<0.25% Pb) in accordance with the Safe Drinking Water Read More
Vibration Isolation in Aquatherm Piping
April 18th, 2018
201804A – AQTTB Date Issued: 18 April 2018 The Aquatherm Technical Guide says, “Aquatherm polypropylene (PP-R, RP(RCT))1 can absorb small vibrations, so isolators are not required if the pipe has some limited mobility on either side of the pump or equipment to which it is connected.” The above statement only applies to small diameter pipe Read More
FLUSHING AQUATHERM PIPING SYSTEMS
March 3rd, 2017
TECHNICAL BULLETIN: 201702A-AQTTB Date issued: 3 March 2017 All piping systems, regardless of their intended medium, should be flushed thoroughly after installation. Flushing the piping system removes particles and debris that tends to accumulate in the piping system upon installation. Particles include shavings and bits and pieces of pipe that are the result of installing Read More
