has acquired the assets of US-based waterless floor drain trap seal maker Sure-Seal, the company said on Wednesday.
Splashing causes aerosolization of waterborne organisms that exist at the top of the trap seal. In areas where patients with compromised immune systems may be present, use laminar flow spout outlets in lieu of aerators in order to reduce aerosolization of waterborne organisms that may be present in the domestic water supply.
"Natralock's outstanding strength and durability ensures the highest quality trap seal blister packaging solution that spans a wide array of applications," said Jeff Kellogg, vice president, Natralock security packaging, MWV.
Clearly, Flush Valve B does not meet the bowl's needs at the end of its discharge cycle, so it does not restore the trap seal. Therefore, both fitting and fixture manufacturers should agree that a specified combination will perform properly at all anticipated building pressures before their selection.
This combination trap seal blocks out sewer gases, and the covering BlueSeal layer blocks out urine odors from the room, according to Waterless.
Newer building exhaust systems typically maintain a slight negative pressure in bathrooms, which can result in trap seal evaporation and, as we have seen, in the introduction of contaminated aerosols into indoor spaces (Ballanco, 2003).
The reverse trap design resembles the siphon-jet but has less water surface, a shallower trap seal, and a smaller passageway.
Retrofit all building U-traps with deep-seal traps or trap seal primer valves.
