AQUATHERM BENDING AND DEFLECTING
June 9th, 2014
In general Aquatherm does not recommend bending Aquatherm pipe as a means of making a change in direction or going around obstacles. However there are instances when the pipe is required to bend. When installing Aquatherm in a directional boring application or when encountering unexpected permanent obstacles in open trench applications, the pipe may need Read More
AQUATHERM BRASS VALVES
June 9th, 2014
The brass-bodied valves offered in the Aquatherm 2014 catalog are not intended for use in potable water systems as they do not meet the new zero-lead requirements which went into effect January 1, 2014. These valves include the brass/PP-R ball valve, the screw–down stop globe valves, the draining branch valve, the chrome plated concealed valves, Read More

AQUATHERM BUTT FUSION 4” PIPE
May 14th, 2014
Aquatherm has recently introduced the 4-in. (125 mm) Blue Pipe® SDR 17.6 faser-composite pipe available for purchase. This product line has been available in 6- to 24-in. diameter sizes for two years – and it still is. However, Aquatherm identified a customer demand for 4-in. Blue Pipe SDR 17.6 to allow for more cost effective Read More
AQUATHERM AND HIGH RISE CONSTRUCTION
April 29th, 2014
One of the eternal truths of this life is that water is heavier than air. It weight 62.4 lbs per cubic foot at 68°F. This mass requires a pressure of 0.433 pounds per square inch to lift water one foot. To put it another way, one psi will raise water 2.31 feet. These facts are Read More
LARGE DIAMETER BALL VALVE CLARIFICATIONS
March 6th, 2014
This bulletin is being issued to clarify the bolt connections and sealing of Aquatherm large diameter ball valves (part #’s 41602 – 41607). As can be seen on the face of the valve, there is an area where it appears a large O-ring can be inserted to help seal the valve connection to the piping Read More
BUTT-FUSING OF DISSIMILAR SDRS
December 11th, 2013
From time to time there arises a need to butt fuse pipe of dissimilar SDR’s. For example many of our 6-inch molded fittings are made in SDR 7.4. In order to butt fuse the fitting to SDR 11 pipe the butt fusion heating times and pressures need to be adjusted to accommodate the difference in Read More
OVALITY IN MACHINE ASSISTED FUSIONS
August 29th, 2013
When using any fusion assistance machine, avoid clamping the fitting in a way that will cause the opening to form an oval shape. The welding heads are designed to operate under very specific tolerances, and compressing the end of the fitting can prevent proper contact, and thus proper fusion. Some bench top machines are more Read More
AQUATHERM AND SOLAR
August 29th, 2013
Aquatherm piping is an excellent choice for use with most solar heating applications. There are, however, a few precautions that need to be observed when using Aquatherm in the solar piping system. The most significant use of solar heating has been for swimming pool, domestic hot water, and space heating. Solar collectors are classified according Read More
Aquatherm Temperature Spikes and Boiler Malfunctions
August 29th, 2013
201308E – AQTTB Date Issued: 28 August 2013 The temperature/pressure ratings in the Aquatherm literature are based on averages over the life of the system. For example, the rating at 180°F would be applicable for a system with a set point of 180°F, with the expectation that the true temperature of the system would fluctuate Read More
