Home & Garden power washing companies

is there any companies in the Dumaguete area that clean driveways and sidewalks? The cement around my house in Bacong gets moldy and the relatives break their backs scrubbing it. Would like to pay someone to clean it every so often.

 

can buy a power washer for close on 7k, that is also a mobile unit and pretty light easy to move around more that do the job

 

Is water pressure from faucets here too low

 

a water tank and pressure pump would give adequate pressure to run a power washer...

 

Black and decker makes a selfpriming washer. If the preasure is basicly gravity or a barrell, and you want it electric, then the self priming feature (regardless of brand) is what you will need.

If you want gas power they can also be made with a waterpump, a hose into a bucket or barrell, and a hose out.

Anothet idea, the next time it is dry, try treating the area with "stuff" (I do not remember the name) to keep the area clear. I am sure someone here knows the name of the chemical.

Personally, I just use bleach and a paint roller. Kills everything about 2 days.

 

I have AC Service guys here today just using a large bucket and electric pump. The pressure they are getting out seems decent enough. Even when the pressure from the tap is good here they still use a bucket (today only as the pressure changes quicker then the wind in Valencia).

 

I found this https://www.washwisely.com/water-supply-pressure/

Some points:

"Even though you’ve found the right unit, you can’t buy it without checking your water supply. The GPM number on the pressure washer has to match the capacity, or the pressure of the water supply. Even if the GPM water flow of your water supply is just a little bit lower than the GPM specs of the pressure washer, you can wind up ruining the unit.

Let me give you an example. You buy a 2.8 GPM unit. This means the water supply the pressure washer is hooked up to has to be able to deliver 2.8 GPM as well (preferably more), because the slightest difference in favor of the pressure washer is enough to damage its pump irreversibly."

[Then he explains this is due to cavitation and then how to check water pressure, which will be obvious to many members:]

"OK, this is very simple. All you need is a 2-gallon bucket if you want to have an electric pressure washer or a 5-gallon bucket if you are planning on using a gas-powered pressure washer, a stopwatch and to be sure a 25-foot, 3/4″ diameter hose (doing the test without a hose is usually good enough though because in most situations you will see a big enough surplus anyway).

Now open the tap all the way and fill the bucket with water. In the case of a 2-gallon bucket, if it’s full in less than 60 seconds you have sufficient water pressure. In the case of a 5-gallon bucket, if it’s at least 3/4 full in 60 seconds your water pressure is sufficient even for the more powerful gas powered washers.

To be more accurate you can also count how long it takes to fill a 1 gallon bucket and then divide 60 by the number of seconds you counted for 1 gallon. So if, for example, it took you 15 seconds to fill the bucket your water flow is 60 / 15 = 4 GPM."

[The problem I have is that water pressure here is variable - but using it from a tank on a tower could help that (although, again, the water pressure will change with the head of water remaining in the tank). Maybe this is a minor issue.]

He also recommends these (not sure if any are available locally):

Perhaps the infrequent use of a power washer would make it ideal as a joint purchase with other reliable (!) locals.

 

In a mild off-topic (how this has improved since I stopped posting so frequently!), who did you use for your AC servicing. Thanks.
