Firstly hi everyone.
I have a petrol power washer with a temperature relief valve fitted. Problem being is instead of opening to release the hot water recirculating in pump will not using. The copper casing failed and it blew apart. Is there anyway to bypass this valve by fitting a new unloader valve so i can bypass water back to drum.

Any help or advice would be much appreciated.

Pictures Help for sure
 
Post an image, but here's the basics..
Thermal Relief Valves don't like Feed Line Pressures over 60psi.
..the cheaper ones blow apart. The rest will Suck Air when starved for water, and Cavitate. That causes the Seals in the Pump to Fail, if the Unloader doesn't Fail First.
Next... they Don't Like Suction- Feed.. They'll Suck Air, and cause the pump to Cavitate. So.. is Converting to Tank-Feed, with Bypass to the Water Tank, Remove the Thermal, and get a Big Feed Line on the pump inlet !
 
As stated above, And .. the newer #ThermalReliefValve doesn't like over 60psi, especially with hardly any water in the bypass circuit.. Releasing the triggerGun, "Jolts" the inlet side of the pumpSystem harder with "nowhere to go" compared to having a big, Long Coiled Bypass Line to allow the dampening of the PressureSpike.
The More Water in the Bypass Circuit, the Longer it takes to OverHeat that water, Allowing the Seals in the entire PumpSystem to a Longer Life, with Less Downtime to Destroy Income. "Little Things" can make a Big Difference.
Also, if you're going to convert to #TankFeed you'll need to Remove the Thermal, and Bypass Directly to the Tank, which Ends Any chance of #BypassOverHeat
..unless you run it Low on Water.
