Dependable Brass Relief Valve

After I put it to the test, this brass pressure relief valve proved to be a reliable and efficient part of my plumbing system .It responded quickly and accurately to overpressure situations. The durable brass construction ensures long-lasting functionality. The only downside is that it may be more expensive than other relief valve options, but the investment is worth it for the quality and dependability..

Pros
  • High-quality brass construction ensures durability and longevity.
Cons
  • The pressure relief valve is not adjustable, which limits its versatility in certain applications.

Not impressed with hydraulics, pneumatics and plumbing

The 3/4" threads were NOT cut properly and my stamp on it mated the fitting. Once installed it immediately began pumping water through the outlet port pull and the pressure in the house plumbing was not approaching 75psi but just under 60psi I bought to depressurize the hose as the sun puts pressure on my hose when the atomizer is off I wish I could give 0 stars.

Pros
  • Lead free brass with stainless steel control springs
Cons
  • unreliable
