The push/pull valves pop into the closed position when pressure is too high which is probably because of the expansion tank failing.
Why would you remove this layer of protection?
You can’t always count on the safety relief valve to work if the pressure gets too high.
In fact the push/pull valves engaged before the safety relief valve released when my expansion tank failed.
Also, it may be the local building code to have these types of push/pull valves installed on these systems. I’m not 100% on this.
I would just replace the hose and push/pull valves every 5 years. It's not that expensive but a hot water heater exploding will be expensive.
If you do decide to swap out the push/pull valves test the safety relief valve once a month as they have a tendency to stick.
It would be nice if they put actually pressure gauges on these hot water heaters. Cheers.
