Shurflo 4048 High-Flow Water Pump is rated 4.3 out of 5 by 7.
Rated 3 out of 5 by from Same old on-off pulsating flow Provided a better flow rate than my old pump. The description "High performance fresh water pump features Flow Reaction By-Pass Technology that produces smooth, low cycling, high powered flow up to 4 GPM at 55 PSI. Automatic demand design eliminates the need for an accumulator tank...." lead me to believe that it would deliver water at a relatively constant pressure. However, it switches on at about 35psi and off at about 55psi. The result is a highly variable pulsating flow.

Rated 4 out of 5 by from Not as quiet as expected This is a good pump and it does what it's supposed to. The install took about twenty minutes and I used the Shurflo quiet kit (flexible hoses between the pump and the hard plastic piping). As long as you don't mind a little noise, this pump delivers the pressure and flow you want. I had a problem with it not wanting to shut off until I found I had an air leak. Once fixed, no problem. Except the noise.

Rated 5 out of 5 by from nice upgrade I replaced a 2088 shurflow , which this is a direct replacement for, in my camper. The pressure is better and the pulsating was gone. My wife loves it . Installation was just a matter of connecting the water lines and hooking up the electrical connections . The screw pattern and size is the same as my old pump .

Rated 5 out of 5 by from Great pump This is not too noisy, has really good water pressure, and primes quickly. The pressure switch adjustment, although small, is easy to adjust and I was able to set it just right the first try. It is well worth it. As for the longevity factor, that remains to be seen.

Rated 5 out of 5 by from Replace existing pump I bought this pump to replace a shurflo 5.7 extreme series that would not prime and once it did would not shut off. Was able to use all existing fittings so installation was quick. I love the pump so far, great pressure, primes quickly no drawbacks that I can see.

Need to replace shurflow 2088-403-144. Will this work?

Asked by: Anonymous
Shurflo's conversion chart recommends a <a href=https://www.campingworld.com/shurflo-4028-water-pump>4028-100-E54</a>(SKU#70516)for a direct replacement. However, a 4048 can be used but will consume more power for the higher flow rate and is marginally larger in dimension.

is the mounting foot print the same as the Resolution

We have a very limited space
Asked by: james
No, the 4048 is a larger pump. You can view a diagram for the 4048 <a href=http://www.shurflo.com/images/files/RV_Product_Data_Sheets/Fresh_Water_Pumps/pds-4048-153-X75.pdf>here</a>, while the 4008 Revolution datasheet can be viewed <a herf=http://www.shurflo.com/images/files/RV_Product_Data_Sheets/Fresh_Water_Pumps/pds-4008-101-X65.pdf>here</a>.

What is the recommended Size accumulator Tank. Space is not a concern

Asked by: Anonymous
If space is of no concern, use the 2 gallon model <a href=https://www.campingworld.com/shurflo-2-gallon-stainless-steel-tank>item# 14747</a>. In limited spaces, use the 24 ounce <a href=https://www.campingworld.com/shurflo-accumulator-tank>item# 2290</a>.

wath is an acumulator tank ??

Asked by: Anonymous
An accumulator tank is a product that is used to help regulate the water pressure to smooth out the pulsating of your water pump and helps to keep your pump from cycling too fast if only a little water is used. This item has those functions built in, so you don't need an accumulator tank.
