Wife and I are renting a home here in Denver. Water pressure at the faucets and showers is terrible. Called the water company and they assured at least 100psi into the house. Bought a Rain Bird exterior psi gauge and at the cold water faucet of the washer and two outside hose bibs, we're getting 38psi.
In the basement is of course the pressure relief valve. I know I can adjust it to increase the whole house pressure, but my rental also has a sprinkler system (drained and off obviously right now).
The main water pipe comes in through the basement concrete, then the PRV, then the water meter, then the split off for the sprinkler system.
(I assume this is wrong in that the PRV ought to be after the split for the sprinkler, but I can't change the pipes as it isn't my place.)
Since I'm assuming the sprinkler was installed with the GPM and PSI measured with the crappy 38psi (or perhaps the original 50PSI or so was then dialed back instead), I'm then assuming the heads were chosen based on the low pressure. Or can ALL sprinkler heads deal with 50psi?
Thus, my question....
If I increase the rest of the house pressure (to say, 50psi) so it's good for the nine months of the year when we don't use the system, will I risk destroying the heads with too much pressure when the system is opened up in the summer?
Or can the heads 'take it' and then simply be dialed back distance wise since I'm assuming (again with the assumptions!) that if I increase the entire home's pressure, the water will shoot too far out of the heads.
But mostly I'm concerned with wrecking the heads or other parts of the sprinkler system (or anything else for that matter) with feeding too much pressure.
