Question: I want to feed a tankless water heater, from a water barrel (rain barrel). for my Polebarn shower. Will this pump do the trick?
Document: So, long story short... The mobile home a friend lives in had such horrible water pressure that the shower barely sprayed beyond the tub spigot and it also took 5 minutes to fill the toilet tank after flushing. The washing machine cycle took over an hour on a large load as well. I asked 3 plumbing supply places if something like this was available and they said no... Liars!!! I also bought...SHURflo 255-313 Classic Series Twist-On Strainer (1/2&#34; FPT x 1/2&#34; ) and screwed it right onto the pump, used braided hoses for a toilet tank and a sink to adapt it into the main line.
I like this product. It worked as I expected and does the job perfectly. It is part of my water recycling system.
If you are used to a water pump in an RV with the noise it makes, you won't have any trouble with this one. Sounds the same and pumps water very well. Easy to wire up.
Used with Triton 10L shower in backwoods cabin, and both exceeded my expectations. I have better pressure in the cabin than I do in my house.
Now the shower hits the back wall, the toilet fills in under 30 seconds, and it's what I consider to be &#34;liveable.&#34;  it was transferring vibration directly to the frame just using the rubber mounts and noisy, but I went back, mounted the pump to a board then used 1' thick styrofoam between the board and mounting place and now it's able to be heard, but not obnoxious. After seeing the difference it made there another friend ordered one for his house and is installing it now.
I used the pump for 10 minutes and the motor died. I have taken it to a pump repair shop.
Great pump at a great price but I also needed a accumulator tank to keep it from pulsing on and off. Fast delivery by UPS.
I connected this pump without issues. It produces good volume and pressure, The demand feature works well and comes on quickly.
The plastic 1/2&#34; inlet valve was cracked or broke vary easily when I tightened it so that I had to epoxy the fitting on never to be removed again. The actual pump work very well.
This &#34;shurflo&#34; pump comes in a generic box not a standard Shurflo box. It is by all indications either defective or a grey market product. Should have known better, the price was too good to be true. Now I have to pay additional money to ship the defective pump back.
Answer: no
